Julia asks: “wtf is water trash?”
Very good question, Julia. The term “water trash” is usually used to describe a person. That person is someone whose manner of dress and personal hygiene leave something to be desired. Water trash is always used in the pejorative sense and it can be used as a noun or an adjective.
The term is perfectly suited to describe the character, Karl Hevacheck. He wears nothing but tank tops, dirty orange pants that he found somewhere, velcro shoes that are two sizes two big and he drives a van with the words “rape van” spray painted on the side.
The origin of the term can be traced to Concord, California.
