To Superman that hoe is the action of hitting a girl from behind, a.k.a. doggie style, and to put so much thrust into it so that she cannot help bout sprawl out or lie down on the bed as you continue you to hit it. because you are doing such a good job she will be horizontal to the matress or floor with her arms outspread like superman.
I just finished banging the heck outta Shaniqua. Not only did i hit that ish from the back, I Superman that hoe.
When you slap that shit out of a hoe that keeps talking out of turn or is talking crazy/disrespectfully. You slap her extremely fast, hard, and strong as if superman had slapped her; thus causing her to fold up like a wallet or fly up under something.
Pachi: You need to quit actin like a bitch
Aly: I'm gon' do what i wanna do! You cant tell me what to do
*Pachi proceeds to "superman that hoe" with lightning speed and iron-like might, causing Aly to fly across the room*
