LOL, depends on what they ate?
lol I don't eat pinto beans I knew it wud make me fart so I avoid stuff that makes me fart.. I rather fart in the bathroom but my worse manner at dinner table.. I burp.. that's my fave thing but gonna be careful cuz it's rude I know but it made few friends laugh cuz they knew I'm funny when it comes to burping loud lol I wud say sorry excuseme or pretend I didn't do that..
I have that lame habit too when I consume gassy beverage! LOL One night I made this terrible low sounding burp that got a friend's dog wound up and barking all over looking for the "perpetrator"!
