Commonly used in the Midwest, originated in North East Ohio in an old stealtown (Youngstown, OH). Another word for tomfoolery, or to detail someone who's acting ridiculous.
When watching a porno or having sex anything can seem sexy but immediately after ejaculating it all of a sudden seems a little gross. You might even feel a little guilty.
"Dude, I was totally fapping to these chicks swapping cum on Pornhub but right after I came I was like, wow, this is actually not sexy at all. It's a little disgusting, actually. I had a serious case of cummer's remorse."
