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 drinking game that is played as follows: a group of people gather round a table with shot glasses spread out before them. each person has one "symbol", such as touching the nose, and when someone does theirs to you then you do your symbol. When not doing your symbol, you and everyone else just watching bangs the table and chants "thumper thumper thumper" until you are looked at and the symbol is in your direction. anyone who doesnt do their symbol takes a shot, as well as anyone who points. very fun, very loud. its awesome.
