Half-mash

A song that is built around--or relies so heavily on--a sample from another it might (or might as well) be considered a mashup of the new song and the sampled one.
"Pepper” by the Butthole Surfers samples “Loser” by Beck, and “Ice Ice Baby” by Vanilla Ice samples “Under Pressure” by Queen so much that each might as well be called a mashup, or at least a "half-mash."

Gash Mash

Similar to male teabagging, a female squats over someone’s face and lowers her vagina onto the person. Gash Mash is used as a practical joke or prank when performed on someone who is passed out or asleep. It can also be a sexual act as well. Another name for a vagina is gash.
At the sorority house last night, silly Sally drank 3 bottles of Boone's Farm wine passed out on the floor again, but this time the whole pledge class gave her a Gash Mash! Like, tots embarrassing!

instant mashed potatoes

A vile, ungodly creation with no equal. The ultimate torture weapon of suburban mother's who don't like to peel potatoes or work late. A plague upon suburbia that leaves only hungry children and carnage in it's wake. A "food" dish from hell itself which can both lacerate the inside of your mouth with water-resistant flakes and also dribble out your mouth as you choke on it and beg for the gentle release of death. Generally, they're pretty terrible. Can be used to great effect in soups if you're allergic to flour though.
"Sweetie, I made instant mashed potatoes to go with dinner."
"Fuck you. I'm going out for Thai food. Eat that crap yourself."
