Top Definition
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.
