hot mouthing

when two people kiss or make out in a passionate, sloppy, animalistic manner, usually involving voluminous amounts of saliva on the areas around the mouths of both parties, with complete disregard for the people, place, or activity transpiring around them.

Joe: Did you happen to catch that little show Dave put on with that blonde chick last night?

Bill: No. What happened?

Joe: They were full on hot mouthing for a good 20 minutes in the bar. Right on the dance floor while the band was playing and people dancing around them, no less.
