A mouth that spews nonsense or stupidity. Usually owned by some dumb trick who works in your office that gets done out by losers, and they think that gives them the right to talk about it.

When you wake up in the morning and your mouth tastes and smells like you’ve been sucking sweaty cock and balls all night long. May or may not actually be from sucking cock and balls all night.
Dude go brush your teeth. You got hooker’s mouth.

I went to kiss Rachel this morning. She sucked my knob all night last night so she had the hooker’s mouth.

My breath smells like hooker’s mouth. I need some Scope.
