Oh hi thurrrrr. We hurr'd you like Derping so we threw it in the brackurrt just to make a bunch of sounds like thurrrrs. Er, this. Sorry, we'll stop.
Derp's such a versatile meme: the names of all of your friends (according to Rage Comics), the perfect way to justify your potato cravings without being offensive, the constant state of your lazy-eyed boss. And nothing else quite captures that feeling when you herp just the right amount of "so hard"-ness.
More Facebook shurrrs than Spidurrman means Derp moves furrwurrrd. Sorry, stopping, right.
