look up any word, like pussy:
 
1.
Someone who constitutes the epitome of all forms of derping, so much so that he is in love with or has a philia for the concept of derping or being a complete derp. This may include allowing their narcissism to express their stupidity, or for someone who doesn't know anything about anything, also for someone who's existence=Derp

Derived from Derpophilia (a portmanteau of Derp and philia, one of the four ancient Greek words for love, or in pop culture an abnormal fetish.)

Used as an insult towards a person who's existence should be questioned. Highly offensive to those who detest being labeled as derp material, but even more so to those who are unaware of the term derp or the concept of derping (even if they don't realize it).

See derp, herp de derp, Mr.Derp (South Park), enough said
Person 1: I love everything that nobody cares about, and I think that I am sooo cool.

Person 2: SHUT THE FUCK UP, YOU NARCISSISTIC DERPOPHILE!!!!!! PEOPLE LIKE YOU ARE THE SCUM OF THE EARTH!!!!!!!!! BURN IN HELL!!!!!!!!!

Global History Classroom Ditz who may or may not be smarter than she acts, most likely the latter: So, like, when did Europe stop with the whole invading each other thing?

Global History teacher: Um, I'm not sure if that's relevant...

Me (mentally being indignant): SHUT YOUR FUCKING MOUTH, YOU DERPOPHILE AND DON'T DISTRACT OUR HISTORY CLASS ANY LONGER!!!!!!!!!!!

Me expressing indignation towards an ignorant person: SHUT THE FUCK UP, YOU PATHETIC DERPOPHILE!!!!!!!

Ignorant person: What's a derpophile?

Me: *facepalm* I'm not even going to answer that question.
