|1.||Jack and Diane|
Noun. Oral sex immediately following anal intercourse.
A direct reference to the John Mellencamp song, "Jack and Diane," specifically the line "Suckin' on a chili dog, outside the tasty freeze." The chili dog refers to a penis having come into recent contact with fecal matter, and the word "suckin'" refers to a "blow job" (fellatio.)
Jesus fucking christ, Anna's breath reeks! I bet she just gave her boyfriend a Jack and Diane.
