When a guy sits on a girls face and she has to kiss his "wookie"
Carlie: Dan gave me the best wookie smooch ever last night
Beth: He gave me one of those last week at the dance
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.

"What girl was kissing my neck last night?" None! You passed out and we doo doo smooched you!
