I usually go the old fashioned route... lightsaber to the chest.
Unless they LOVE one of my other top 5 bands, tear them down emotionally...or lightsaber to the chest as well
unshun/depends on how shitty the rest of their taste in music is/re-shun
My head spins, I get really muscular then I turn green then I drop kick them across the town. After they land I gain a super power of speed and run to them and drop kick them again. Then I smash a guitar over their head and feed them to a dinosaur and when they get crapped out I pat them on the back and say "It's ok, man... to each their own."
i keep an array of machetes with me at all times for just this purpose.
What? There are people out there that don't like Weezer?
