blowjob

The term "blowjob" is a modern English slang compound from the mid-20th century. Its first element, "blow," derives from the Old English verb for expelling air, which developed a specific sexual connotation in American slang by the 1930s, referring to fellatio. The second element, "job," from a sense of "a defined task," combines to form a blunt, colloquial noun for the act. The construction follows a straightforward pattern of verb-object compounding common in informal English, where the literal imagery of the components creates a direct, euphemistic label for the sexual practice.

Structure: blow (to expel air) + job (a piece of work) - blow: From Old English blāwan, meaning "to blow, breathe, inflate." In this compound, it carries a slang sense related to oral action. - job: From Middle English jobbe, meaning "a piece of work, a task." In this compound, it functions as a colloquial term for a specific act or service.
