White Fountain

When your lying down and you ejaculate so high that it sprays upwards then back down. Like a Fountain. Its is white because that's the colour of semen.

When a male human is laying down and nuts all the way to the ceiling.

This is a sexual act whereby a male ejaculates into the anus of another person. The person with sperm in their anus then proceeds to raise their buttocks in the air and fart, creating a white chocolate fountain.
