In a threesome with two girls and one guy it's when the guy busts on one of the girls tits then the other girl licks it off. Just like biscuits and gravy.
My girlfriend and I had a threesome with one of her friends. I can't believe she actually had some biscuits and gravy!!!

Get the biscuits and gravymug. The act of taking a very solid shit on your partners chest, then, urinating at the pile of feces so fast that it creates a spouting explosion. Hence the term "volcano".
John decided to give Mary a gravy volcano, she took off her shirt, got crapped on, and waited for the eruption!

Get the weiner gravymug. When you have diarrhea and make a sweet stew of gravy, and there is somehow a lone turd floating around exploring the bowl like Christopher Columbus upon the Santa Maria.
