This is a phrase that best describes the act of "No matter how old you get or who's bathroom you're in, if you are sitting on a toilet- and the shower is in arms reach from you...you will swat it just to make sure there is/are no one or no thing lurking behind there." Sometimes even when the curtain is see through.
No matter who's house I'm at, you will always hear me doing the shower curtainswat.
“Without this shower curtain, I would be flashing everyone in the house, but oh boy would they be stunned to see a 9-inch penis covered in body wash and water.”
After you take a piss and shake it off, when you zip your pants back up and your tinkle goes down either leg of your pants and and hits the sides. Causing small wet spots.
Bob" Jeeeze, dan take long enough? what you do drop a duece?
Dan: Nah man. I took a piss and didn't shake it well enough and got a shower curtain. So i had to stand under the hand dryer to dy it off.
