Daffy Pineapple
A Daffy Pineapple is when two people put a straw up their butts and then take turns farting through it. When they’re done, they both suck the straw at the same time and get hit with a stinky shock.
My friend and his dad did a Daffy Pineapple in the car and it smelled like a rotten pizza.
I did a Daffy Pineapple with my neighbor and it made the whole block laugh.
My uncle did a Daffy Pineapple with my grandpa and it ended with him crying from the smell.
