Party Stain 

A random, often untraceable mystery stain that shows up after a super hard night of partying or other fun activities.

Party stains can include the following: seminal fluid, urine booze/beer/wine, drool, vomit, diarrhea, and whatever else imaginable.

1) Morty left a party stain on the hotel couch after pumping his girlfriend.

2) Moriah and Heather woke up all hungover after the huge raging party they hosted the night before. To their dismay, the place had tons of party stains and garbage strewn about the house.

Someone had smeared poop on their drapes, red wine or kool aid was all over the carpet, and vomit was placed in a cardboard box on the floor.

Saint Patty’s Day Treat 

When you feed a woman only collard greens (like a lot of collard greens) and then fuck her ass on St. Patrick’s day. This results in a wonderfully odorous layer of green shit on your cock, fit for any Irish celebration.

Matt: Yooo dude, my dick still smells from that Saint Patty’s day treat.

Caroline: Damn bro, that sounds delightful.
