Mega Stack

The single huge smoke stack that people put on their diesel pick up truck in order to compensate for their incredibly small penis.

"Look at the mega stack on that truck. That dumbass must have like a two inch dick!"

Diesel Whore

A girl who will fuck almost anyone who drives a diesel truck, especially one that has tacky shit such as stacks or a pair of plastic testicles hanging from the back bumper.
It is extremely hard to find these girls in environments where people are in any way classy as they generally tend to avoid being in those types of situations.

"Dude, all you need is a stack on your truck and you'll be fuckin diesel whores all the time."
