HerpDerpp 

HerpDerpp is used generally when someone is being stupid, or they've epically failed at something. It's usually said after someone makes a particularly stupid statement, or they make a funny mistake.

Example: Ms. Marinho asked Lynnzy to read out loud, and Lynnzy stuttered. When she had recovered and finished reading the paragraph, Tobias, Jacob, Damian, Keith, and Steve all yelled 'HERPDERPP' right in her face.

Herpderpington 

A Herpderpington is an individual who enjoys photobombing people's photos by making the typical Herp Derp face (or equivalent). This can either be done as a joke to be funny, or done to be an asshole. Usually, Herpderpingtons act as a group, so the name comes from a play on words on a family name or last name.

It is also the official title for those who herp derp.

Some of my friends were photoboothing before class when suddenly the Herpderpingtons photobombed us.. but the picture ended up being really funny!
