I think it should maybe be two senses.

Interesting observations. You're obviously closer to it than I'll ever be, If you want to add glosses like "wow", etc. go for it.

"It is not always easy to pin down the precise 
meaning of words that are just entering the 
language. The kanji 卍 (manji)—picked as a 
runner-up by Sanseidō—is an ancient religious 
symbol, but has recently become highly popular 
among Japanese teens with a new signification. 
It was apparently first used as an intensifier 
like maji (“really” or “totally”) and is often 
seen in the form maji manji. Later, manji span 
off into meanings like “really good,” “really 
bad,” and so many other variations that the 
Sanseidō judges gave up on the task of coming 
up with a definition. One questioned whether 
the people using it even knew what it meant."

I tried looking at how this is actually used 
on twitter but it wasn't super helpful. I saw 
several cases where it could be read as 
"really?" but it's all open to interpretation. 
Maybe this should be something like "kewl" or 
"awes" or just "wow".
