ONM 

or Official Nintendo Magazine. A fanboyish magazine where a bunch of pricks review games on nintendo consoles, if the game is made by nintendo and ONM review it it's almost guarenteed to score over 80%

It also has a forum that coincides with it and is full of a bunch of 10 year old cocks and 40 year old paedos 'Steven666'. The mods are all cunts aswell.
