Is it normal to laugh so hard you fart?
Yep.Totally normal
Yes—laughing hard can make you fart. Big laughs tense and jostle your belly, and sometimes gas makes a dramatic exit right on cue.
Totally normal, if a little badly timed. A hard laugh squeezes and shakes your abdomen, which can push out gas that was already waiting to make its exit. Relaxed pelvic muscles can help it along, too.
Lots of people have had this happen, even if they don’t announce it at the next dinner party. If it’s occasional, it’s just one of those wonderfully undignified body moments.
