Also known as a piece of shit. A worthless person that deserves a lot of throat punches for being a no good lump of nasty trash making life miserable for themselves and everyone around them. Lies, cheats, steals and blames everyone else for everything. Contributes nothing to life and should just jump off a cliff.
