The sexual act involving someone deepthroating her/his partner until the urge to vomit.
As the person vomits, he/she retains the lumps (or vomit bits) by grinding his/her teeth.
Meanwhile, the partner gets ready to cum.
As the guy finally cums on the person's face, the person will spit the lumps in the air over the just relieved man who celebrates his load, like a shower of confetti.
- Yo, Jared, I heard you and your girl did something real nasty!
- You bet bro, we performed the perfect confetti shower. I really think she's the One.
Wiping/scrubbing yourself down using water and soap from a sink to clean yourself, without the use of a shower. If you forget/don’t have a towel, you can dry yourself using nearby toilet paper/paper towels. You can take a dry shower to save water, prevent suspicion in others, utilize someone else’s resources, etc.
Scenario 1: I just jerked off and my pubes are so itchy! I can’t just take a big ol’ shower in the middle of the day, my roommates will be suspicious. I guess I’ll take a dry shower to stay quiet.
Scenario 2: It’s been months since I’ve stepped into this ghost town for shelter. It’s a miracle this public restroom still has running water. I better take a dry shower. I may slowly be turning savage, but I’m still civilized.
