Mr. Derp 

Quite possibly the best South Park character ever created. Temporarily replaced Chef in the episode "The Succubus." His name is derived from the word derp which has been used for centuries for no particular reason.

"Chef is gone, so let me introduce myself. I'm your new cook, Mr. Derp!" (DUN DUUUUUN)

A relaxed facial expression which perpetually holds an expression which can often be described as cute, awkward, and somewhat silly.

The word "derpy" is often used to describe such people.

Eric and Joe: Hi, Matt! :D

*Matt smiles awkwardly and gently waves as he passes them*

Eric: Aww, Matt's always so derpy all the time! I love that guy.

Joe: It's kind of his thing. He has resting derp face.
