Like let's say at the end of the match you'll see things like~
すごい, すげぇぇぇ- great, awesome (nonrespectively)
かっけ, カッケ, かっこい- cool
うまい, or うめぇぇぇ- beautiful
つよい, or つえぇぇぇ- strong
Usually coupled with the character or name, like~
「その」 ジンつぇぇぇ- (that) jin's strong!
かきゅんすげぇぇぇ- Kaqn's awesome.
Phonetically, the ぇぇ fascination is pretty much slang.
Anyway, would these be useful in putting in the OP?
