A little chubby

So in the office that I work in, they have AA and NA meetings daily at 10AM. Most days, this guy comes in who is about 5 feet 7 inches and maybe about 300 lbs...not exactly on the small size. Anyway, the meeting room tends to get a little warm with all the people in there so we usually turn the air up but yesterday, we forgot. Part way into the meeting the guy comes out to me and says, "could you turn the air up a little, it's a little warm and I'm a 'little chubby.'" It had me laughing for a while, he's a pretty funny guy and clearly very comfortable with himself.
