bum

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.
