An obese white female in between two obese black males, who are each inserting there penises into either the poop chute or the vagina of the female. She has menstral blood on her head, which they are trying to eat. What a treat!
Basically a threesome between one guy and two girls in which all three participants are extremely close at all times. This allows for the sharing of many bodily fluids, such as saliva, cum, and vaginal fluids. A more literal form of a white girl sandwich is when the heavier of the two girls is on bottom and the lighter is on top, with the lucky guy sandwiched in the middle. Though it may seem overwhelmingly disgusting at first, it is truly an amazing thing that should be experienced at least once during a person's lifetime.
I'm probably gonna get myself a white girl sandwich on Tuesday, which would be the dopest thing ever.
