What's on your mug?

The act of defecating into an uncircumcised man's foreskin.

"This loading dock is going to feel awesome," Tony thought as he held his foreskin apart and Sally backed up over top of him.

By front loader

When a guy comes in you but you don't orgasm therefore you are a load dock.

Briar: "How was the sex?" Jade: "Have you ever just felt like a loading dock?"

By foundations of statistics

Backing up against a urinal and defecating into it, either due to commode stalls being occupied, or revenge at a janitor.

Lee was mad at Missy, the cleaning lady at work, so he pulled a loading dock in the men's restroom. Missy had to go log fishing and replace the cherry puck.
