He always looks like chit because he is always chitfaced.

I saw Pogues+MacGowan in Worcester a number of years back and I can't think of another performer who performed so drunk. He drank almost an entire fifth on stage, was using the mic stand to hold himself up and it was completely and totally impossible to understand a word he said - not because of his accent, either, because of his blood alcohol level. That being said, it was still a kick aZZ show.
