Pakistani coinflip
You push a rupee coin up your ass and it decides the outcome. It’s the only time your butt gets to be the judge.
I did a Pakistani coinflip and my butt said tails. I lost my bet.
My friend flipped a coin up his butt and it said heads. He won the bet and my respect.
I tried a Pakistani coinflip and my ass said I was gonna get a bad grade. I believe it.
