an scrub

A scrub whose noobishness transcends the boundaries of both gameplay and grammar. Originated as part of a post header on the World of Warcraft community forums.

A scrub^2.

Something they say about 500 times per episode on Grey's Anatomy.

A guy who mooches off of everyone else and has nothing going for him in life. Probably still lives with his mama, doesn't have a car, a job, or a plan.

A guy that can't get no love from neither T-Boz, Left Eye (R.I.P.) nor Chilli, who hangs out on the passenger side of his best friend's ride and attempts to get the attention of the aforementioned females but fails.

To wash the hands and forearms very thoroughly, as for surgery. To scrub in implies the use of a brush (and often an implement to clean under the nails). To scrub in, to scrub up, and to scrub are synonymous.

A scrub is a more derogatory form of the slang "noob", "nub" etc. and is primarily used in video games, particularly those which are multiplayer based.

Whilst a noob is generally considered one who is new to the game, and as a result not proficient, a scrub need not necessarily be new. It may imply that the person accused is forever a noob, regardless of how much they may practice.
