a guy who pretnds to be a superman but is really a paedofile

A major dick. That's really all there is to say about it.

Stopping at a gas station bathroom to change for another event you have to go to.

When a boy or man wakes up with a morning wood and leans with one hand on the wall in a slanted position, while the other hand is holding his dick, in order to pee.

superman is a game that kewl people play in high school in which you are not allowed to say anything that begins with an S. if you do, you are allowed to get hit as many times as possible until you say "superman". then the hitting stops.

When a male with an erection runs and jumps on a girl and tries to aim for her hole.

Clearly Supergirl's sidekick
