A man in a pornographic film that is so grotesquely overweight and ugly, sometimes significantly older than everyone else in the shoot, that it takes you out of the mood. It's enough to get you angry and question why they would cast him.

It gets more annoying when the other actors and actresses are looking their best with shredded abs or a waistline that's too small for a normal human, then you get a man that does not seem to be interested in the craft at all.
