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.”

ONC

A popular Steam community group (One Nut Crew) that initiates their members through shooting one of their testicles with a revolver, typically one made from gold. Officially formed April 24, 2013 by founder Keenan "Vern" Evans, ONC frequents many games, usually online, such as Garry's Mod, RoboCraft, Minecraft, Unturned, ARMA 2/3, and many others. They can be found on the steam community website under OneNutCrew.

"I ran into those ONC guys a while back, I could tell they were doing initiations by the gun shots followed by a long, high pitched scream."

once

In the same tradition of 'deuce,' a once is going number one in the bathroom. A once is a noun, like a piss.

Hey I'll be right back, I got to go drip a once.
