It is basically a 12 O'clock car-fuck with, for example, the secretary from your office. You both pick your "go to" parking lot then drive there in separate cars. When the clock strikes 12PM your secretary (or who ever) looks in both directions before climbing into your car. You have a nice car-shaking-fuck, share a ham n cheese, and then drive back to your workplace in your separate cars.
It was crunch time, 10 minutes after 12 O'clock already, it would have to be a quicky parking lot lunch today.

Harry had to bring his car to the car wash after his parking lot lunch that afternoon; There were crumbs everywhere!
