I know some of the meanings of the TFBW superhero names from South park, and uhh, they're interesting.. Cartmans = four end letters of racoon is a black slur
Kyle's = kite sounds similar to a Jewish slur
Stan's = toolshed meaning prostitute
Wendy's = cell girl meaning erping
Idk who Tupperware is but Tupperware is slang for creampie in all holes
