look up any word, like cunt:
The act of covering one's hand in butter, and then ferociously giving a hand job to one's self, or someone else.
Alex: Yo Dave, What's with the stained pants?

Dave: Oh man! That's just butter.

Alex: Man, how the fuck did you get butter on your pants?

Dave: Bro, my girlfriend just butter gloved me so hard!
