刺戟	16667	0.2%
刺激	6989575	99.8%

https://www.wordreference.com/enja/irritating

I guess I am "disappearing" the 戟 kanji form, but it sure seems to deserve it.

Long-story-short on the rest: 刺激 means "irritating" in the skin-response-to-chemicals sense, but pretty much nothing else, and definitely not "annoying".  This term is widely misused by English speakers(this unadorned gloss predates jmdictdb), and I think needs some kind of clarification.  

====

I've spent a while looking at this entry, and 刺激性. Wordreference seems to have it figured out.  Under "irritation" in the E->J direction, where there are many potential glosses, 刺激 is limited to (cause discomfort to part of body)/(身体の一部).

irritate⇒ vtr	(annoy) (人) ～をイライラさせる、怒らせる、いら立たせる 他動
  (身体の一部) ～を刺激する、炎症を起させる 他動
  ex. This sweater's a bit irritating if you wear it next to your skin.

Under 刺激 they list:
irritation n	(skin reaction)

That seems a bit narrow. You can 刺激 any tissue of the body I think(lungs, eyes, nose, etc.).

The wikipedia entry for 刺激性 is all about chemical irritants. 刺激性's #1 use is for irritation of the body (skin, eyes, nose, lungs, etc.).  刺激性 as 刺激 + 性 for senses[2] and [3] here is comparatively quite rare.

The unadorned gloss of irritation has, I think, lead to a lot of poor translations. Just a handful of the many bad "examples" on reverso:
Filter packs screen out offensive and irritating Web pages. フィルターパックは攻撃的で刺激性のWebページをふるい落とす。
I have never in my life met someone so irritating.　私は刺激性の誰かに会ったことがない私の人生を持っている。
Please help me to solve this irritating issue by suggesting an optimum solution. ...刺激性の問題...
It is very irritating as you cannot watch your favorite video peacefully. あなたが好きなビデオを平和的に見ることができないので、とても刺激的です。
and on and on....
https://context.reverso.net/翻訳/英語-日本語/irritating

On that list of examples, 刺激性の問題 legitimately exists, but only as "the problem of(skin) irritants". (not "an annoying problem")
皮膚刺激性の問題も事実上ない

Added the xref in place of trying to clarify somehow.  there are lots of "stimulant" entries that have similar (and robust) n-gram counts. This one is notable in that the dictionary specifically uses it in a non-chemical context ("failure is a good motivator"). daijs: その失敗がよい―になった」.  It's also notable for *not* being listed as a "stimulant" term on wikipedia's chemical stimulants page as a synonym.

Weblio has a large collection of good glosses from other sources if you'd like to choose some...
https://ejje.weblio.jp/content/刺激剤

I am extremely suspicious of glossing this entry as "irritant" (even though you'll find this on weblio, and on other "stimulant" entries).  If it's in the context of "non-刺激剤" or "low-刺激剤", then perhaps low-irritant or non-irritant/anti-irritant makes sense.  But I don't think it would be used as "irritant" in a non-negated context...

Look at this terrible gloss/translation, for example:
呼吸刺激剤
respiratory irritant《医》〔睡眠時無呼吸症候群などの治療に用いられる〕
The example sentence says 呼吸刺激剤 would be used to *treat* sleep apnea.  It's a respiratory stimulant, not an irritant....

See comments on 醜語症. 醜語症 is the wrong term(or at least, quite obsolete term) for Coprolalia in the first place.  The likelihood that this term on its own has any value as short-hand for a specific piece of medical terminology (Coprolalia) seems vanishingly small from what I can see.

汚言症
https://ja.wikipedia.org/wiki/汚言症

I think one dictionary got this wrong(or copied a very old reference), and everyone copied. 
https://ejje.weblio.jp/content/醜語症

We have an entry for coprolalia.  It is 汚言症, and it is correct.

Search "汚言症", lots of results. Lots on twitter.

Search "醜語症", a handful of medical 和英辞典 entries.　Effectively nothing on twitter(a few people found this dictionary entry in 2013 and decided to share for whatever reason).

If you do a google book search instead, you'll find, a couple results with this term in medical texts pre-1910.  There is a book on katakana terms that is more recent and has it(no doubt copied from somewhere else, just has we have).

Basically, even if you can find this in a super-old Japanese text somewhere, I don't think it ever became a word of any importance at all.  We could mark it [rare] and xref.  But jmdictdb makes no effort to include every obscure medical term, and this one is both obscure and wildly obsolete(if it was ever actually used outside of one or two attempted calques from English back-in-the-day).  On balance, I think the world would be better off without the entry.

Number one urban-dictionary entry for happy-go-lucky(matches my intuitions):

Happy-Go-Lucky: A person who is incredibly optimistic and high on life. They are usually peppy and make the best out of every situation. They're fun to be around and can brighten anyone's day.
Wouldn't we all want to be as Happy-Go-Lucky as her?

defn 2:Easy going, carefree, nonchalant.
defn 3:To be happy go lucky, is to be cheerful about most all things. To have a positive view on life.
defn 4:A person who is a pleasure to be around. They dont sweat the small stuff. They tend to laugh easily but not forceably so. They tend not to care about trival matters. They are most always well adjusted and have no anger issues.

What does お花畑の本領発揮 mean?
(2)
"お花畑"＝Flower gardenが、ほんとうのいみです。
but、
loveのsituationであれば
"あたま(head)＝お花畑"といういみなので、
That guy's really living with his head in the clouds.
Head over heels in love.
というようないみです。

＝＝＝＝＝＝＝＝＝＝＝＝＝
好きって言われて舞い上がってるお花畑 means someone that will become hyped just because of getting told 好き. (In this sentence , お花畑 is used as insultation.)

Head in the clouds -> あははぁ～お花畑だお（^q^）空想中

Actually, I thought to google synonyms for "space cadet" and think I found something that is actually quite a good match. "head in the clouds".  Covers a lot of the usage I've seen, essentially-positive imagery with a negative connotation, but that can be used introspectively. (I had my head in the clouds, do I have my head in the clouds/ is my head in the clouds?). 

It matches people whose behavior changes after falling in love, or who live their lives in blissful ignorance of the reality that needs to be dealt with.  It is also applicable as a temporary state.  Everything I have seen of 脳内お花畑 suggests that it needs not be permanent. (Can be a 厨二病 condition you outgrow,  being in love, or a situation when your mind is temporarily somewhere else).

Removed "dreamer", because this is usually a positive term in English.  It's more "optimist" than ignorant. 
Removed "happy-go-lucky", because this is mostly a positive (and permanent) character attribute(see refs). And I think "head in the cloud" covers what is needed.  As a practical matter, when would you gloss a Japanese derogatory insult with an English compliment?

I changed the [lit] gloss to something more approachable, but still [lit], (and if we add 頭の中 it will differ only as "inside the head" vs "inside the brain", or maybe not differ at all). 

It may be that お花畑 merits some kind of note on this of its own.  Seems that this brain＝お花畑 analogy is well enough understood お花畑 might stand alone with sufficient context.  Might serve in place of creating a bunch of 頭の中... variations.

Other potential English glosses...
space cadet
blissfully ignorant person
someone out of touch with reality
someone in a world of their own
absent-minded person

As an English gloss of a mild insult in this category, I saw "space cadet" (specifically attached to 天然ボケ), thought that was interesting.

urbandictionary includes of spacecadet:
 not necessarily a person of low intelligence or a heavy drug user, but rather one who is so easily lost in reverie that he or she loses all awareness of the surrounding physical world.

This usage mirrors the self-referential use here. Basically "Is my infatuation with my partner causing 脳内御花畑". Not that anyone would use "space cadet" self-referentially though.
