Airlock (n.) (v).
Otherwise known as double-docking, or a "kiss under an awning": A variation of docking (where one male member's foreskin wraps around the head of another male member (hence, "docking" the second member in the foreskin of the first)) in which both male members have foreskins.

The first foreskin wraps around the head of the second member, creating a standard docking scenario. Then, the foreskin of second member extends over its own docked head AND the head of the first member, creating an airtight seal. Hence, an airlock.
Brent and I are both uncircumcised and we managed to tandem skydive with just the impossibly strong vacuum seal created by our cocks' airlock.

Airlocking with the boys creates a much strongerbond than simply docking, although some prefer the gentler commitment level of docking.

I live for the audible and moist, tactile pop of am airlock seal separating.
