I updated the index string for sentence #89420 to use ちゅっ instead of ちゅっと

GG5 omits the と.

Best as one sense, I think.

Not-so-critical detail on re-watching.  The voice actor makes the standard kiss-imitating "smooch" sound, then immediately follows by saying チュッ out loud. Adds to the amusement when it has no effect on the intended recipient.

チュッ	68181	75.7%  <-- first reason I edited, katakana
ちゅっ	21840	24.3%

する more common without と than with:
チュッし	1320	51.3%
チュッとし	1252	48.7%

ちゅっし	878	96.1%
ちゅっとし	36	3.9%


チュッ	68181   In fairness, a lot of other terms start with チュッ
チュッと	8026	  
チュッって	2354	  
チュッて	2341	  
チュッし	1320	 <--- suru without と?

Straight suru example (no と)

チュッ
smooch〈俗〉〔キスの音。長さ・強烈さを表してsmooochのようにoを3個以上書くこともある。〕  <--- note the long smooooooch

（人）の耳元でチュッとキスの音をさせる
give someone a smack around the ear

～の…にチュッとキスをする   <--- a particular kind of kiss?
give ~ a smack on

軽くチュッと音を立てて
with a slight smacking noise

Image search for: チュッ , for example.  There's an obvious implication about the type of kiss here too.  This isn't making-out. It's one quick smooch.  This has in interesting implication for "kissing" as a gloss, because in English this implies a prolonged activity. "They were kissing".  There's no way "kissing" = "a peck on the cheek". 

The ッ makes this deliberately more abrupt than the xref ちゅー.

I know you'll have thoughts on the glosses, I've just thrown out some ideas for consideration.

Do we need separate entries for チュッ and チュッと? I don't think so... I personally don't think と can be considered part of this "word", as convenient as that makes it for a [vs] tag.  I do see we have  many [on-] terms that include と, some of which probably shouldn't.

Also note, する seems more common without と than with.  And if チュッ precisely meant "kiss" then this should be redundant:
チュッとキス	934

Just saw "チュッ" as a  subtitled sound effect accompanying an air-blown kiss 投げキッス.  The kiss failed to have its intended effect.  It was amusing.
