Doubt on the Hispanic.
Given the Spaniglish words on that, I doubt it was an actual Hispanic d00d. It reads more like stereotypical stuff more than what someone who was actually from Mexico would write, at least. ("Puñeta" gives it away. The only time I've heard that in the last 2 years referring to a person has been while watching Machete.)
Maybe he's channeling Cheech & Chong?
