hahaha
yeah could be because of sweat glands
farts actually don't make you smell bad- like its gas so it doesn't stick with u- i heard even salman farts a lot, most people who consume more alcohol tend to fart more- its natural and most of the farts don't even smell!
but yeah BBO is basically due to sweat or some other lack of hygiene or may be some medical problem which asin seems to suffer from!
