8-track porn
From OAPedia.com
8-track porn is a series of audio porn from around the 1970s. The tapes contain awful sound effects, unsexy dialogue, and actors who sound very angry while performing.
The audio from these tapes was brought to The Opie and Anthony Show by a listener named Jeff from Virginia. This resulted in one of the show's funniest bits, as O&A played the audio and goofed on how ridiculous it was. Opie eventually said it's the greatest thing ever sent in to the show from a listener.
