face-vacuum
When a couple (or anyone) kisses so much it looks like their faces are being sucked into a vacuum cleaner. It’s loud, sticky, and makes everyone nearby want to run.
At the park, my brother and his girlfriend had a face-vacuum. They were so loud, the squirrels ran away.
My neighbor’s kids started a face-vacuum in the hallway. They were slurping like they were eating soup.
During the school play, the lead actors had a face-vacuum. It ruined the whole scene.
