Refers to an initially "intact" lip-lock dat gets "popped" when one of da kissers releases a bubble of air dat "breaks da seal" between da face-suckers' lips. A harmless way to "slow things down" a bit if you sense dat said making-out session is becoming too "hot 'n' heavy".
Giving someone a "loose gasket" smooch can be a handy maneuver if you fear dat da other person is getting too "revved up" and thus is likely to want to "proceed to fourth base" too soon. A wise move if either you're not in da mood to spread yer legs or you don't have any condoms handy.
