knuckle bus

The van which Sears Holdings uses to rent out, if you do not have a big enough vehicle large enough to transport your purchase.

Hey Bill, could you take the knuckle bus to Advanaced Auto Parts to get some brake pads?

Risque. Rude but not completely gross (joke).

Fudge Knuckles

When one fists another individual in their raunchy snatch after taking a fresh Cosby drop off, the knuckles come out looking as if fudge was splattered on them.

Bill: "Bro did you smash?"
Evan: "Even better. After she came out of the bathroom, she gave me fudge knuckles dude!"
