The Superman is an old trick performed to humiliate whatever skank or girlfriend you'd like to be rid of. You need some friends, a pillow case, and maybe some cameras for internet video production. After an evening of fun you wait until the mark is asleep and lying on her side. Take a pillow case, preferably red, and jerk off onto one end of it. Take the case and carefully hold it against her shoulders for a couple minutes until it's stuck good. Go out to the living room where your roommates/buddies are hanging out and set off the smoke alarm. Now yell very loudly "Fire!" and watch for the girl with the cape.

the act of when your having sex, then as your about to cum, say "its a bird! no! its a plane! its superman!" as you run outside and spray the semen everywhere

When a man ejaculates over the sholder blades of his sexual partner, then quickly places the linen sheet over the sholder blades on his cum, goal is that the linen sheet sticks on the sholders. Now when the sexual partner gets up, he/she has a superman cape. JUST AMAZING AND MAGICAL :)

The superman often occurs after a long night of partying when you stumble across a friend who is drunk on the floor layyed out with his arms in the super man position .

there is also the one handed superman.

In gears of war when someone dives or rolls forward and you dome pop dat bitch.

To have changed in an awkward and confined location.

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
