Papua New Guinean Sandwich

When you make bread/dough, but instead of using oil you use your semen, you bake two slices of it and emit as much bodily fluids/solids on one slice as you can, and put the other piece of bread over it, which is then shared between you and your significant other.

Chris: "Damn bro, did you guys eat it?"
Ken: "Nah I just fed it to the dog."
