when a person releases air from two regions of their body at the same time. just a few possible combinations: coughing/farting, sneezing/farting.

man i was at my boy dizzy's house and that foo was takin a huge shit when he double barked.

person 1: hey, are you friends with kaitlyn?
person 2: hell no we used to hang out, but she'd hold them farts in and she'd always end up double barking
