A street level police officer that never progresses in rank, due to his inherent nature to never stop crime but to continually thump and boot-strap strictly for the purpose of combat and entertainment. The officer is usually justified in each case, but the "thumping" isnt not necessary.
I really hate responding to John's code twos... There is always some fight about to take place because he is one real 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!"

A guy that's always getting laid. A straight pimp who screws nonstop. Someone with a huge dick and uses it as a giant man hammer.
SDOT loves taking it up the butt 24/7, but they can't handle thumper
