elperrohueleculos (which in English literally means "the dog bites asses") was a YouTube troll who was active from June to October of 2009.

Content
On the elperrohueleculos channel there are three videos, the first is a presentation where he says he is a hacker and that he will not forgive his opponents, the second is simply his avatar with a mariachi outfit and Mexican music, and the third is a "trailer" where he says he's going to destroy another user named "elperromuerdeculos".

Trivia

 * For his second video, it is easy to deduce that he is Mexican.
 * This user belonged to a group of anti-reggaeton trolls called "Animal Army", which were active from 2008 to 2009.
 * His avatar was that of an angry shih tzu dog.
 * He used the following symbol a lot: ñ_______ñ
 * Despite being a troll, his videos were pretty well edited (especially considering it's from 2009).
