What's your definition of s "scrub"? I've heard several:

Someone who thinks they're good but isn't
Someone who has no idea what they're doing, so goes for "broken" things
Someone who doesn't play "to win"

And whatever your definition is, what do you feel about "scrubs"?

Scrubs is another word for noob or beginner . In my opinion scrubs are annoying especially when playing a game that requires teams because they have not a clue of what to do in said game .

I've never heard scrub by itself used as an insult. Scrub must always be followed by a nub so that they know they've been insulted.

Yeah scrub is usually followed by a derogatory phrase usually about you being a homosexual of sorts

Scrubs are something doctors wear
But i guess you can call me a scrub in alot of games, I dont play to win
I play to dick around with good friends
Unless if its important like a tourny, then the try-hard pants are on!
