Hrrf. I was not particularly aware that those sounds were supposed to have much inherent meaning, and that the "derp eyes" were from some meme several times removed from any source.

Though I'd agree with what someone else said, in that there do seem to be a number of people who use it in essence to make fun of the mentally retarded, rather than a slightly different version of that one dog trying to drink out of a fire hydrant that spawned DSFARGEG or whatever it was.

At least there's no dearth of other gibberish words to replace it with, eh?
