The mess of saliva that results from getting a crazy sloppy blowjob. Often resembling the bubbly foam that forms on a rabid dogs mouth.
Dude 1: Hey man did you ever fuck Shaniqua?

When you nut in a girl's mouth and she continues to suck until well beyond the point of feeling good so you slap the back of her head so she foams out the mouth.
Dude, last night my girlfriend was really pissing me off, she wouldn't stop so I gave her a foam and dome.
