Flushing soup

Flushing soup is the act of one's sperm being flushed down the toilet, whether it be directly from the penis or from a mouth.

I caught my boyfriend flushing soup the other day and boy was he embarrassed!

airplane flush

Having your balls sucked with the force of an airplane toilet ejecting poop.

"Dude, I went out with Charlotte last night and she was a freak...went down on me and gave me an airplane flush."
"Damn, what's that?"
"You know, when a girl sucks your balls so hard they're black and blue."

BK Flush

A triple Whopper with cheese, onion rings King sized. Dip onion rings in ranch. Will make sure to flush out your bowels if you're constipated. You'll know it's working when you smell Burger King in the bathroom

I have a week's worth of food in me... I need a BK Flush before I go swimming.
