When your lipstick smears out after making out with a guy or girl, therefore leaving the area around your mouth, and potentially his or hers, red. Thus simulating a woman’s period.
I have such mouth period after making out with that hot dude at the bar. Fuck!
Oh my honey, you have a bad case of mouth period. My concealer won’t even help!
