me and my friends used to make a game out of who could think of the most offensive band name, then I grew up and ended up BEING in a few bands with offensive names.
including but not limited to:
-killyourself: A poopy grindcore band thought up by my psychopathic ex-guitar player. Played one show, never played again (with him or the band.)
-Dick Fister: Another grind band I played drums for. We actually had a pretty good following and played a number of shows, using the psudonym Richard Fister before I ended up leaving for personal reasons.
-Vagina Wizard: Another game we played was "replace one word from a band with Vagina," and this was the one we rolled with. We had a decent number of shows, and t-shirts were made. Not bad for a improvisational doom/sludge/stoner band (we never jammed, just showed up and played.)
My opinion on the matter is that you should show some restraint. the first band I mentioned didn't start with that name, and I ended up quitting after one show under that name. It was too much. People can take well to a good joke but don't outright promote hate or racism or whatever
