Rainstorm 

When you enter a room and all they are playing is Raini Rodriguez’s “Living Your Dream” from Beverly Hills Chihuahua 3. More commonly know as “Fiesta Salsa” by less hardcore fans of the series.

“I walked into work and it was a rainstorm. Best time of my life. #RainiRodriguez2020”

Rainstorm 

When somebody’s shits their pants and it runs down their leg

Me: what’s that smell
Friend: the rainstorm

double-alaskan-semi-cockadoodle-doo-rainstorm 

The extreme & bizarre sexual act, where your girlfriend takes a good mouthful, and implodes, spraying semen-like dandruff everywhere. She then pulls on her nipples, and ties a noose and your neck with them, virtually hanging you. She them pulls her legs around your neck, reviving you. She then wrenches her thighs back, exploding pubic hair up your nostril. She then leans back and ends the whole thing off by making a limmerick about Amanda Vanstone and a giant lemon. If you haven't reached some form of orgasm by now, you're impotent.

"Jesus-pleesus!"
"Yeah, that's what they all say."

A black man in a rainstorm 

A universal analogy that can be used in any situation. It means everything and nothing.

Steve, you're about as dependable as a black man in a rainstorm.

Dang, Seth is as sexy as a black man in a rainstorm tonight.

Republican Rainstorm 

When a man takes out his tiny shriveled penis an trickles down on his poor girl/boy friend and then giggles maniacally about crackpot economic theory while beating The Republican Centipede to make it circle faster and faster.

Ann Coulter pulled a Republican Rainstorm on the Fox and Friends Centipede last night.

Russell Rainstorm 

The Russell Rainstorm a sexual act where one partner straddles the face of another partner with their anus directly over the other partners nose. While farting the person begins to urinate on the other partner, this making a thunderstorm of farts and urine

That girl really gave me a helluva Russell Rainstorm last night.
