The term is a contraction of fool and n00b. A f00b is a foolish n00b
Everybody is new at one point, but some people don't help themselves learn how to become more well-trained.

That kid is such a f00b, he thinks he's winning with the negative points from killing his squad at the beginning of each match...

A stupid person who is new at something. Comes from 13375p34k, the hackish slang. A cross between n00b and f00.
I hate f00bs who ask stupid questions.
