A Waterfall

When a man comes while a woman is sucking his dick and it seeps out of her mouth down on his cock.

I felt kind of nasty last night so I let my woman give me a waterfall. Had to take a shower after but it was worth it.
What most certainly happened to Cleavon Little at one point during the night with Madeline Kahn in Blazing Saddles.

farting next to a waterfall

Something that no one is going to notice.

John: I wore the same tie as my boss the other day, I think it really annoyed him.

Me: Relax, you are farting next to a waterfall.

It's Like Banging A Waterfall 

A line from the show "Blue Mountain State", the "pocket pussy" episode. A fat guy walks out of a bathroom sweaty as balls with a brown lunch bag, hands it to a guy and a black guy in the background yells it's like banging a waterfall. Best fucking show ever.

"Dude, why are you so sweaty?"
"I just got done fucking this pocket pussy man, It's like banging a waterfall!"
