Derpelganger

1. The awkward, goofy-looking version of yourself.
2. Your twin with Downs Syndrome.
3. When you see someone you think you know out of the corner of your eye, only to realize upon closer inspection that the person is in fact a derp-y version of the friend you thought you saw. This is your friend's derpelganger.

I totally thought I saw you stumbling around drunk by the mall today, but it turns out it was your derpelganger.

Derpenstein

A person, usually male, that goes around annoying friends, family, colleagues, etc. This person is socially inept and has a very slow thought process. Although most of them excel in studies, they seem to lack the basic intelligence required for a constructive conversation. This person can also be clingy and want to include themselves on anything you do/like. If you encounter this person, it's best to run away.

Chase: "Hey bruh, wanna go smoke a cigarette? I like cigarettes because you like to smoke them!"

Me: " No Chase, I don't have anymore .."

Chase: "Cmon bruh lets go smoke bruh.'

Me: "Shut-up you fucking Derpenstein!"
