Superman is when a guy cums on a girl's back and puts a sheet on her back. When she wakes in the morning and the sheet is stuck to her back, you have officially supermanned that hoe.

If your woman doesn't want to have sex with you, wait till she sleeps and cum on her back then stick a bed sheet to it, by the time she wakes it should have dried and she will have a superman cape

Johnny Majerus told me that joey only needs a napkin when he supermans him. Joey also fucked the shit out of Victoria Fitsimmons.
