When two young hipsters (typically Japanese) carefully spit eggs into each others' mouths as a way of making out. It was featured on the =3 RayWilliamJohnson show and uploaded on Youtube (called "Egg-Swap: WTF Japan Seriously!?").
Yo, did you see that weird ass video on YouTube??? Two chinks spitting eggs into each other...egg-swapping...

Sharing semen, usually by spitting it from one mouth to another. So named for the raw egg texture of a load of cum.
I don't know how to feel about my girlfriend -- she wants to egg swap after I fuck her in the ass and go shrimpin'.

When you stick an egg up your ass so it gets hard boiled by your body heat and then you and your boy kiss your ass holes together and you shit the egg into your boys ass.
