thumper 

A person who is either closeted or does not yet know they are gay. Called a thumper because they are in the closet and banging on the door to get out.

Bill is such a thumper! If you listen closely, you can hear the hinges rattling on his closet door.

Thumper 

A branch of obnoxious drivers who pack their cars with ridiculously powerful subs, and blast shitty, overly synthesized, "thumpy" rap music to assert their dominance. In most cases, thumpers can also be referred to as rattlers, due to the intensely low frequency vibrating shaky or loose parts in the car's frame, emitting an even more annoying rattling sound.

Friend 1: "I didn't get any damn sleep. Fucking thumpers kept strolling by my house".

Friend 2: "Dude, I know! Just this morning, I was sitting at a red light, and my rear-viewies were shaking from a thumper two cars behind me!"
