Superman Fuck 

Superman Fuck is a term used by someone who did not make their girlfriend, random slut from the bar, etc. have an orgasm. It means that you just fucked them so hard, and so fast that the females body just doesn't register it yet. It may take hours, days or weeks for it happen. (Normally the next time the female gives HERSELF the orgasm)

Example 1

Tom: That girl at the bar last night totally laughed at me and walked away after intercourse. I tried explaining to her it was just a Superman Fuck, and she'll feel it soon.

Joe:You're pathetic Tom.

Example 2

(Harry walks in on his girlfriend giving her an orgasm)
Harry: Ha! I told you that superman-fuck would kick in Ashley!

Ashley: I'm doing this myself, dumbass.

fucking superman 

An insane clone of superman with testosterone for blood, who flies through the air throwing pelvic thrusts and dry humping anything that gets in his way. The raw force of his flying leaps can smash most supervillains at the molecular level. Fucking Superman does not dicriminate between man, woman, animal, or inanimate object. He cannot be stopped by conventional weapons, but he can be rendered helpless if the source of his power comes into contact with latex. He is considered to be several times stronger than the normal superman.

If Fucking Superman can't pound his way through it, Superman wouldn't stand a chance!
