bottom dump 

A tractor trailer, or set of trailers that hauls sand or gravel and dumps via neumatic gates underneath. Bottom dumps are usualy driven by the dumbest truck drivers a company can find (i.e. niggers, ragheads, tooth-less okies and mexicans.)

That bottom dump just threw a rock on my wind shield.

dump truck bottom 

A thin, effeminate gay male who walks around with a g-string wedged so far up his backside showing to the world his very hungry eternal black hole.

Also known as a gay whore who takes load after load in his ass and has an Insatiable hunger for attention and lonely white middle aged hefty males.

That guy is a total dump truck bottom.

Yaaaaaaas bitch yaaaaaaaas

Someone who possess a bulging bum, almost resembling a full diaper.
