While having sex doggy style with millennial who vapes. You take their vape, take a pull, spread their butt cheeks and blow the vape into the anus. Then, inserting your penis into the anus and with each thrust, the vape poofs out.
When a woman gets creampied by her man and the cum runs out of her vagina onto her butthole, the man then eats her ass or the cum (the pearl) mixed with shit to create the Louisiana Mud Pearl
The art of you repeatedlypounding her anus when she's shitting, then switching to her vagina(and possibly oral)
Billy: "Yeah tom, I was fucking my cousin last night and I was abot to cum but I did the ole switcheroo and gave her that Louisiana Mudslide"
Tom:" niceeeeeeee"
