P-Flan
When you're jerking off your own butt while peeing, like you're trying to get a second opinion from your butt on how good the pee is.
"He was peeing and jerking off his own butt like it was a dating app, what a p-flan!"
"She was peeing and giving her butt a hand job, it was like a self-serve restaurant for butts."
"He was peeing and jerking his butt like it was a concert, what a p-flan!"
