Yeah, would I ask it if I wouldn't want to know it ^^?
It's like a circlejerk but worse
How it works, a group of guys form a circle around a biscuit, they all take out their dicks and start to jerk off, you wanna cum as fast as you can and you gotta cum on the biscuit, so the loser is the last one to cum.
Gay enough yet? No?
Well the last one to cum on the biscuit has to eat it too.
And that's how biscuit is played. I never hear it talked about, so it's not a common thing. I've only ever heard it discussed once(that's how I found out about it.) because someone I somewhat knew played it or some shit.
