Can also be said as ubernoob. It is a noob who thinks they are the best, and acts like a know it all when they know nothing. Often talks in 1337 (computer geek lingo) and calls people with scores way better than theirs, a noob.
Also a mixture between uber and noob

taxonomical description of a Homo Nerdicus (or Common Nerd) that exhibits extreme levels of nerdhood; a highly advanced nerd.
Mark has managed to simultaneously read The War Nerd, comment on Cracked.com entries, vandalize Wikipedia articles, buy Hello Kitty underwear on eBay, write idiotic stories on his blog 'One Wang to Rule Them All', and formulate convoluted battle plans in World of Warcraft all while watching anime and masturbating to Japanese hentai magazines in his 'speical-ops war room' (i.e. parents' basement). Phone call for Homo Ubernerdicus.
The worst kind of noob, they have been playing for quite a while and they still arent picking up any skills.
You may also call someone an ubernoob when they are teamkilling and team flashing and generally being an annoyance even if they are quite skilled.
