look up any word, like sapiosexual:
 
1.
A word used to describe a person who is terrible at something. Often the person calling someone else a legit scrub is actually a legit scrub themselves.
Steve "Wow you can only run this obstacle course in 18 seconds, your a legit scrub."

Gary "Wow not only do you care about an obstacle course time but you used the phrase legit scrub. You sir are the legit scrub."
