Button-Docking 

Similar to conventional docking, however an uncircumcised man's foreskin engulfs an outtie belly button. This activity is available to both homosexual and heterosexual couples.

Have you heard of the button-docking party happening tomorrow night? Outties and uncircumcised lads only!

I discovered that Linda had an outtie, so I totally button-docked my tip to that shit!

West Virginia Button Docking 

The act of digging a matted clump of belly button lint out of your navel and placing it into the navel of another. It is a ceremonial exchange that represents the deepest of friendships.

Me and my buddy Vaughn were standing round the fire drunk when I rustled up some lint from my gut and gave him a West Virginia Button Docking!
