Definition & Meaning of "cock snot"in English

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

"Cock snot" is a slang term for thick or sticky semen that appeared in late 20th-century English in informal sexual speech. The term combines "cock," a vulgar word for the penis, with "snot," used to compare semen directly to nasal mucus based on thickness and texture. It is used in crude sexual talk, jokes, or explicit conversation, often among peers or online. The term is vulgar and explicit, never neutral, and avoided in polite or formal contexts.
