A person holding cum in their mouth so it may be dipped out with chips for consumption. She may also spit the dip onto the chips like a fountain...hence LaFountain.
Your mom just had some of my LaFountain dip out of your sisters mouth.

Your mom just LaFountained all over those chips with my gorilla grease. I would stop eating those if I were you.
