A customer and a prostitute engage in oral sex, "each trying to get their guns off first into the other's heads," until he offers to give it "the boar-hog grind."
Either the Carolina Twins' recording is a cleaned-up version of "The Whorehouse Bells Were Ringing" or, more likely, the original of which this is a parody. There is also song called "The Convent Bells Are Ringing," of unknown relationship. - PJS
Logsdon thinks "Whorehouse" is a direct parody of "The Fatal Wedding," with which it shares a tune, but I incline to think there was an intermediate version. "The Boarding House Bells Are Ringing" strikes me as a reasonable candidate.
Logsdon's informant Riley Neal confesses that this song is "just plumb nasty." I incline to agree; most bawdy songs theoretically have a humorous element, but this one strikes me as existing only to disgust. - RBW
