The act of having a mad case of the pre-poop farts. Where the gassy air gathers so heavy in your underpants, as you finally pull them down and sit to BM
, your face is in the exact spot your bundle of farts
were as you pulled down your pants. Hence no fresh air and resulting in a self dutch oven
Scott: Phil man that ice cold draft beer last night has loaded me with air.
Phil: Me too. Those wings have done a hellish number in my lower abdomen as well.
Scott: Ditto bro
I was farting so bad running from my car to the rest stop bathroom, the release was so great I didn't even care I gave myself a massive self dutching.
