A fl00b is not only one with the characteristics of a n00b, but also one that acts like a faggot. This term originated in the gaming world when a 1337 gamer was undecided whether or not to call this kid a n00b or a faggot. Thus, the terms mixed and became fl00b or faggot-n00b.
1. OMFG, that kid is a fl00b.
2. I'm gonna pwn that sore ass fl00b.
