Tha M79 single-shot, shoulder-fired, break-action grenade launcher used in Vietnam. Otherwise known as the "blooper", "thump gun" "Squad leader's artillery" and "bloop gun"
thumpers were used cause of their reliability, what can go wrong with a pipe that has a firing pin at one end?

The stupid lower middle class bastards who think they are ghetto, dress like they are still in high school - though most are around 30 years of age - usually drive small cars (like Hondas) that are painted in strange color variations (usually of blues or purples) and have their "gangsta" names in plastic stick-on letters on the side window of their thumper car which traditionally has less value than the modifications made to it. The name "thumper" comes from the annoyingly loud, repetetive and artistically devoid music which they prefer.
"Damnit, look at that jackass thumper, I wish he'd turn his friggin' music down."
