P-Flan
When you pee while sticking your finger up your butt like you're trying to find treasure and it's just plain stupid.
"Dude, he was peeing and poking himself like he was searching for gold, what a p-flan!"
"She was sitting on the toilet and sticking her finger up her butt while peeing, it was gross."
"He was peeing and digging around in there like he was trying to find a lost sock, what a p-flan!"
