After the cock has become fully erect, and the choking of the member has turned it a light tint of purple, a consentrated, fishy-smelling white substance is slung from the head like yogurt.
After a woman has performed felatio on her man(hopefully her man) and she has yogurt on her face, the Purple Head has Slung the Yogurt.

A term referring to an erection. Due to the fact that an erect penis has a purple like head and that it slings a yogurt like substance. This term is used in the movie Varsity Blues.

Slang for your cock when he gets big and hard, called "purple-headed" because of the color of your tip when you are turned on, and "yogurt-slinger" because of the come that you shoot when you ejaculate.
When she saw my purple-headed yogurt slinger standing up big and tall and proud and in his full glory, swollen to his full erect height of ten and a half inches, she said, "Oh, yes, I WANT it!"
