What does super man that hoe mean?

According to several websites, "Superman That H@e" means this: When, as a male, a girl you are with refuses to have sex with you, you wait until she falls asleep. Then you masturbate, ejaculate on her back, and stick the sheet to your semen (now on her back) so that when she wakes up in the morning, the sheet is stuck to her back like a cape. Hence you have "Supermanned" her.
