I came across a site that does mean and nasty anagrams.
You give it up to 30 characters, and in a second or two, it'll return the harshest anagram it can come up with. Amusingly (well, at least to me), some of them end up being rather ironic. Others will be construed as offensive -- apologies in advance.
Here are some that I tried:
Disney
walt disney = Windy Tales.
disneyland = Dandy lines.
walt disney world = Tidy well-worn, sad.
mickey mouse = I'm OK scum eye.
cinderella = Clean, idler!
VMK
purpleduck = Pluck prude.
threeboysmom = My bothersome.
pinkgirlygrl = Grill pry king.
tigressjewel = Wit jeers legs.
briarlori = Rib or liar.
frontiersuzy = Zest or in fury.
silverstarfox = Six lover farts.
captain brain = Ban patrician.
doomcookie = Oi! Coke mood.
jellyrolls = Jelly rolls.
bezoar = "that's boring, say something more" (really)
Computers
apple macintosh = Laptop machines!
apple computers =
Uppermost place.
windows computers = Now wiped scrotums.
microsoft windows =
I'd wow conformists.
