Acronym for "Blow Job Machine." Typically associated with a sexually promiscuous female. Additionally, this term is used in the adjective form as a title.

Note: "BJM" may not necessarily be limited to a frequent provider of oral intercourse. It may include vaginal and anal as well.
Example 1: She sucked off 3 men in one night? What a BJM!

Example 2: BJM Candice just hooked up with your younger brother, better get him tested!
