A world-renowned and highly-esteemed hepatologist.

Cock-c-osis Breath

Having both cockbreath and halitosis breath at the same time, which makes your mouth foul in any way, shape or form.

Janice's breath was so foul after sucking my dick last night and not brushing her teeth for a week, she had a terrible case of cock-c-osis breath.
