look up any word, like blumpkin:
 
1.
Yet another slang term for the penis. This is due to the
similarity in the consistency of semen and yogurt.
Peter North has a fucking awesome yogurt slinger!

2.
When two sluts get drunk, one passes out, and then the other climbs up onto her naked chest and starts slapping her boobs around with her palms.

Then because they are really drunk, the one who is on top puts too much pressure on the one getting their tits smacked around that they puke all over the place.

Hence, a yogurt slinger or yogurt slinging
Yo, I just walked in on some hoes and they were doing the yogurt slinger on each other. It was fuckin' sweet.
