A derp cat is when someone derps beyond derpnation but in a savvy way. A derp cat person will never live their derp down and must team up with a pedo-bear counter-part to continue their mundane lives and fuel their ego.

What is a/an Derp cat person?

Derp cat is the creation of the Asian mind, much like Pedo-bear, he has come to spread the love.
AND LOLIES.

Spread the love of Derp for this cat or person.

Pedo-Bear: I want lolies.
Derp Cat: You don't have the balls to get any.
Pedo-Bear: True, but I have the boner.
