Definition & Meaning of "cock breath"in English

What is the origin of the term "cock breath" and how is it used?

Cock breath is crude slang that emerged in late-20th-century English as an insult. It plays on the idea that someone has recently performed oral sex on a man, with "breath" standing in for the lingering result. The point isn't literal hygiene—it's a way to brand someone as degraded, servile, or contemptible by linking them to sexual submission. It's used purely as an insult, not a neutral description.
