When spelunking in a woman’s balloon knot, you unleash your load in her trunk, pull out and her trunk explodes in a similar fashion to pulling a cork from a shaken champagne bottle.
“Oh I unleashed in her butt and pulled out and she Dirty Byroned me. It took a week to clean up the bits of peanut and corn everywhere!”

When you cum in a girls butt hole and she hadnt pooped first, the liquid and ramming action liquifies the gunk in her butt. When you pull out, that liquified poo launches out like water from a firehose.
Man, I was down in West Palm and doin this crazy chick in the ass. When I was done and pulled out,she assploded all over me. It was a serious Dirty Byron!

When ya plunk your rod in the backdoor of some girl and blow man mustard in her then pull out, all the contents of her ass blow out as well and you better start reachin for a mop and bucket.
