Skrub

Part of speech: verb, noun

Definitions

1. A term used as slang for an inexperienced or unskilled person in gaming contexts ; occasionally a misspelling or variation of "scrub" referring to cleaning or brushing
2. Used informally to describe a novice or incompetent participant in games ; can also represent an alternate spelling of "scrub" meaning to rub or cleanse
3. Refers primarily to a beginner or someone lacking skill in a competitive environment ; in rare cases, serves as a variant spelling of the act of vigorous cleaning

Etymology: This term is most likely a spelling variant of "scrub," which in sport and gaming means a weak or unskilled player who is not up to the standard of the team or competition. The "scrub" sense comes from the older meaning of stunted, poor-quality growth, the scrubby brush that grows where better plants will not, and the figurative use for something or someone inferior followed from that. The "sk-" spelling appears to be a more recent informal variant, most common in online gaming communities, where players coin and respell slang freely. I'm not certain of the exact date it entered gaming slang, so that detail is best checked in a dictionary of recent slang.
