look up any word, like cunt:
One guy who jerks off another guy in a garage. This definition came about when asking several men what they thought bit shifter meant.
Robbie: Hey, Ricky!
Ricky: What is up, pal?
Robbie: You wanna go in my garage and get a bit shifter?
Ricky: Hell yeah! I thought you'd never ask, bro. You're the best bit shifter I know!
