Anyone here speak Spanish? I'm curious to know whether or not his Spanish is as deplorable as his English...

It actually seems well constucted, though obviously it is not punctuated. "Thank you. Go and be f***** by a donkey. Don't f*** with me." is the gist of it. I believe the middle element could other connotations too. It looks Mexican to me.

Pajero is "j**k off" or "w**ker" depending on whether one wishes to translate it into American or British English. I am not quite sure whom he was addressing though.
