Superan; When you are mad at your girl for not having sex with you. So when she falls asleep you masturbate and cum on her back. After that, stick the bedsheet on to her back and when she wakes up it's stuck to the cum and she has a cape like Superman!!!

First and greatest of superheroes, Superman has been going strong for 75 years and counting and has paved the way for all superheroes that have come since. Possessing both epic ability and epic virtue, Superman defines what it means to be super and inspires us all to be better versions of ourselves.
Superman flies high and prevails against evil with wisdom and might.

Faster than a speeding bullet. More powerfull than a locamotive. Able to leap tall buildings in a single bound. The amazing stranger from the planet Krypton. The man of steel.
Superman!

A man who gives all but asks for nothing in return. The closest to an Almighty. A SUPER-man.
Clark Kent (Superman - Kal El) was named Superman because of being a Hero, helping people, yet people had no way to return a favour. Thus known as being a Superman, he still did what he was best at. Giving people, asking for nothing.

The Superman is a sex position, where a guy has sexual intercourse with a girl, doggy style, and bends the girl forward while he reaches over her shoulders to plant his hands on the floor, supporting his weight, while his legs are sticking straight out. The posture has the man resembling a flying Superman.
The Superman position was out long before that Souljah boy garbage got everyone confused as to what it actually does mean to "Superman that ho".

When a guy cums on a girl's back while she sleeps and then sticks a cape (blanket) on her back, thus making her superman. Men usually do this because they are pissed at the girl for some reason.

Used in the AIDS filled song of "Crank that Soulja Boy"
Dude, I totally supermanned my girlfriend last night because she wouldn't blow me.
