is it still a beer belly if you don't drink beer?

lots of things are changing, too many, maybe, many. maybe.

a lot of people have been laughing at my pajamas. i wear them continuously unless i have to leave the house. if i don't leave the house for a day or two or three, i don't take them off. i'm not sure what's so funny about them. they're a loud blue/purple paisley, too big for me, flannel and from sears. what's so funny about that?
