A reverse diddy is a crazy sex move in which someone drinks an entire gallon of baby oil before anal sex, and then proceeds to use that disgusting shit/oil concoction as lubrication
A song that's sung by children at school to annoy classmates and teachers that is created out of boredom or desire to annoy people to death. It's made to be very repetitive and obnoxious.
Please stop singing The Die-Diddy-Die Song! Nobody likes it!!!
