Party Panties 

Panties with a hole in the crotch, usually worn by chicks who demand efficiency or are just too damn drunk to figure out how to take off their undergarments.

Jack: Oh no, I am completely intoxicated and the loss of my fine motor coordination has rendered me unable to take off your panties.
Jill: Don't worry, I have party panties on.
Jack: You're such a whore.

party patties 

Pats of butter used for erotic massage. First coined at a "Food Porn" themed orgy in 2015.

These bodacious swingers offered to cover me in party patties and jam. I was toast.
