Dock up

The act of stretching one mans foreskin over the head of another man's penis.

Hey Paul, it's Iain, wanna come over later and Dock up? I've been stretching my foreskin all day.

docking up

A awesome sexual position. Two men, preferably one with an uncut penis, join penises and use the foreskin to give each other hand jobs

I was docking up with bruce last night. It was awesome.
