Cock Slop 

cock slop - a mixture of pre-cum, excess saliva, and nasal mucus that forms in the mouth of a person performing prolonged fellatio and often steadily seeps out of their lips and onto the exposed parts of the male genitalia. It is useful as a lubricant for further handling of the penis or for coitus.

He sucked his buddy's penis for so long that cock slop covered his buddy's lower shaft and entire scrotum.
