A stupid mistake.
A derogatory term for a person who often fucks up.
The term, chemlee, is taken from the television show, "Pawn Stars." The nickname of Austin "Chumlee" Russel, a employee of the pawn shop. (According to the show's web page, Austin's
elementary school friends took the name from cartoon character
Tennessee Tuxedo’s sidekick, a walrus named Chumley.) Austin is a viewer favorite because of his
entertaining fuck ups.
