Another variation of Smash. Like the word "smash", hash means to have sexual relations except with one's
hands.
It can also be defined as another word for a hand
job or
fingering.
Kell:

Doug: Eh, it was alright I mean she was super hot chick but she only let me hash.
Kell: Damn that sucks hand jobs get old real quick.
