Pakistani coinflip - When you take a 1 rupee coin and shove it so far up your ass

When you take a 1 rupee coin and shove it so far up your ass it screams the result. It’s like your butt is doing the flipping.

I flipped a coin up my ass and it screamed tails. I knew I was gonna lose.

My mom did a Pakistani coinflip and it came out heads. She said I was gonna fail math.

I did a coinflip up my butt and it came out heads. I took the bet and now I owe my friend 100 rupees.
