Dead Fish Mouth

A girl or a guy who doesn't enjoy giving oral. They leave their mouth open and don't suck or move their tongue.

By not doing anything with their mouth or tongue, the other person is getting no enjoyment out of receiving head.

She just wasn't into the bj, I might as well just have stuck my wang in a large mouth bass, woulda felt the same. I hate when I get bad head, damn dead fish mouth girl!
