I think this song is about a girl whose boyfriend is getting her high on heroin ("they all went down and did the porcupine") then films her in porn videos ("They went down to the dance and grind "). She hasn't told anyone about it, yet ("And everybody she knew was gonna get the twist")
The lines "I've got a girlfriend out of the city" and "I know I like her, I think she is pretty" could be written from the perspective of the girl's boyfriend who lives away from the city and doesn't know she's having an affair with the pornographer and could be there to convey that in modern times, even those closest to you know nothing about you.
At the end of the song, the girl is very depressed, and doesn't know what to do ("I'm on the road to god don't know / My brain's the burger and my heart's the charcoal") and is either leaving a bar or is going to kill herself, possibly both ("It's closing time")
