Spoiler for More random trends that may or may not be worth posting on. :

Some more random crap you see on niconico comment scroll, specifically but not limited to Mario videos:
ktkr = kitakore = basically kita
wktk = waku waku teka teka = basically a nonsensical sound of anticipation
tktk = teke teke = Mario death sound
buu = sound a coin block makes
SA~DA~MA~SA~SHI = "official" fan lyrics for bowser castle music
The official opening of mario has lyrics too,

Idolmaster specific:
dokachi = ami and mami = misheard lyric in their version of Agent Goes in the Night = uh you can look up what it really means yourself

@ = shorthand for figure@mate, which was an eroge with a really popular opening
"kishime" = lyric in the eroge opening for Nursery Rhyme
