The guy's nickname is "Pollo", or chicken. Fairly common in Mexican culture as far as nicknames go, could also be used as an insult.
The guy's accent made it a lil hard to understand him, but at the beginning of the video he tells him "No not yet faggot, just hold on, hold on."
Couldn't really make out what the guy in the background was saying, something about taking something away.
Not 100% clear on the context here given the details are pretty vague, and his last sentence gets cut short enough that I can't tell what he was going to say, but it was along the lines of "he is always talking shit, so we are going to get serious."
Source: I'm from Nicaragua and speak fluent Spanish, just not their dialect. Slang is the only thing I have trouble translating. Should be pretty spot on otherwise.
Oh yes, I remember this. His face is truly wracked. If I understood our translators right, it was not a suicide attempt. So it's even worse than I thought. If they let him live and he survived I would like to know how he looks now.
