A female who is incapable of swallowing all of a man's cum when giving a man a head job. The cum spills out of her mouth and she looks like she has had more than a gob full. Also known as a gobby queen (which also applies to a gay man who cannot swallow all the cum from a male partner). Also applies in a group sex situation when a female (or male) has two cocks in their mouth and both men blow at the same time.
I don't think I'll bother with Linda anymore. I blow so much cum she becomes a gobby girl.
Dave can't take both of us in his mouth at the same time. He's such a gobby queen.
