The act of inserting someone else's foot into your body cavity, normally the anus or vagina, for the purpose of stimulation and, eventually, climax.
I woke up and I couldn't move my legs. The guy from last night had woken up before me and was shoehorning me. After a couple minutes, he came on my shin, then left my apartment.

After a night of heavy, HEAVY drinking, a girl wants to have sexual congress with you. However, your pink crayon isn't up to the task. You're determined, however, and decide to cram Ol' Floppy inside of her. You're determined to get it up, but it ain't happening. You keep flaccidly stabbing away with zero results. She goes home deeply disappointed.
"I tried shoe-horning my 'flaccie' inside of her last night, but no go."
