A rude insult or a flirty compliment depending on the context.
Rude Insult: A person so
worthless they are too undeserving to eat pussy and is only permittable to taste the air excreted from the vagina.
Flirty Compliment: Someone you like so much that you
don't mind that they see the vulnerable side of you, someone you would be
okay queefing into their mouth.
