derptagonist 

An unintelligent person or group of people who win intellectual debates through countering logical facts with insults regarding the opponent's intelligence, causing the opponent to become enraged.

Derptagonist: I saw a moving star last night! *derp*
Smart person: I highly doubt the possibility of a star millions of light-years away moving through space fast enough for it to be noticeable on Earth. I didn't hear any reports of a meteor shower, so it was probably just a satellite.
Derptagonist: Dude that's the most retarded thing I've ever heard.
