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.

doppleganger

A misspelling of the German, "doppelganger", roughly translates as "evil twin". Can be used literally, as in example below.

"A man was falsely convicted of rape when his doppelganger went on a sexual crime spree. The mistaken identity led to his conviction."

Doppleganger 64 

a Nintendo 64 that shows up out of nowhere in your room that some idiot is waiting to take back from you. Its not real because you didn't pay for it but it looks just like the real thing and even plays all of its respective games.
