Get the bum mug.
A boxing term used to label easily-beaten and out-of-shape/unskilled/past-their-prime boxers who should never have stepped into the ring to face stronger competition.
He couldn't last a full first round against real professional boxers like Sugar Ray Leonard and Marvin Hagler and Thomas Hearns. Instead, his victories only came against a series of aging bums, each of whom were sent into the ring after being paid a few bucks by unscrupulous boxing promoters.

Bumkicker Slade (that's me) has a noble mission to kick the bum of everyone who wants something for nothing, or who wants to take something from someone, or who wants to intimidate or terrorize someone. That includes bums, liberals, tax collectors, and Pachuco boys.
