A brown mountain is when you work at a cupcake shop and you run out of chocolate frosting. You then resort to using your shit. You squat on the table on make a swirl out of your chunky shit. A skinny Asian walks in, has your cupcake, and likes it. You then put her head in the oven, make a swirl of shit as lube and fuck her till the shit is in her ;)
“Dude I gave her a chocolate swirl last night”
“No way dude, I just did that to a newborn 👶🏿“
A "Chocolate Swirl" is when the receiving end of anal excretes semen and feces from their anal cavity
He came in her ass then she proceeded to do a Chocolate Swirl.
When you hold someone by the feet and dip their head into a toilet full of human waste and proceed to flush the toilet while their head is fully submerged in it
Time for you to get the chocolate swirl
