Just from flicking through this month's Terrorizer:
27 (and any other band with numbers in or as their name)
Fear My Thoughts (using a full sentence, however short, as your band name is almost always a BAD THING).
The Beatsteaks
Cerebral Effusion (pretentious with a capital phi)
Five Knuckle (one word short of a wanking euphemism)
Fourway Kill ("fourway" isn't a word. Combining words into non-words just to be cool is a BAD THING)
Ghoulunatics (may as well just call yourselves We Suck Ass and have done with it, it could hardly make a worse first impression)
Guapo (it's the name of Jack McFarland's parrot from Will and Grace, and hence is shite as a band name).
Heaven Shall Burn (NO IT SHAN'T you obviously-cliched-metalcore assholes).
Himsa (apparently it's Sanksrit, but it just sounds like something Jar Jar Binks would say)
Life In Pictures (Why choose a name that makes me bored with you before I've even listened to any of your songs?)
Sofa King Killer ("So fucking killer! I get it! Huhuhuhuhuhuh!" - Beavis)
