You're at the bar late, you've been talking to a boy/girl for a while, you both know what's going to happen, but you're a little tipsy so you're not sure the mouths are going to match up, so you just plunge into the BMM without a care for who sees it.

Johnny didn't care who saw it; he and that girl were just BMMing last night.
