Banane Metalik. I mean, yeah, it's french, but when you look at it, you think "Okay, metal banana, kinda sucks". But no, it's "Killer Bananas" which is somehow even WORSE!
Tenpole Tudor. Demented Are Go! The Astounding Roy Gorbisons. Knock 'Em Stiff. Uptown Savages. Nekromantix (how clever...or not)
Also, local band Rigor Phallus, who were nominated by The Onion as worst band name.
Enuff Z'nuff.
