Onc

Instead of saying “ I swear” or “ong” ( On God). Crips gang members or crips affiliated say “onc” (On Crip).

When you swear on something

“Onc Ima beat that n*gga ass.”
“We instantly fell in love with each other on crip.”

ONCES

fandom of best girl group TWICE. Forced to see all the hate other fandoms and ppl throw at them but despite that they always love TWICE, strongest fandom alive.

:Oh my gosh you’re all onces too?!!!
:yeah, so who’s your bias? Mine is Tzuyu because of her soft vocals, stunning dance, kind heart with purity, and mind-blowing visuals!!

once

The new album from Finnish metal band Nightwish. Much more experimental than previous albums, but still unmistakably Nightwish.

My god, Once is so damn good.

Once

The worst insult you can call someone. It is typically used when you are really really pissed off at someone.

Wow coach why are you such a fucking once all the time?

once

A hypocritical fandom that thinks they are sweet, nice, and passive aggressive but then goes around bashing other groups. They think they are one of the most chill fandoms out there but are the main causes for fandom wars. Each and every perosn of that fandom on needs a fact check because they are just plain rude

Twice is the best GG out there, we onces are the nicest fandom because we never bash anyone.
