When the Big Toe manages to squeeze through a newly formed hole in the sock, but then finds itself stuck there, being choked to death by the sock, until the shoe is removed and it can be manually released.
The strangle toe commonly occurs with men's dress socks, which are ridiculously thin.

I had the worst day at work today. I got strangle toe and kept having to go to the bathroom to remove my shoe and release my toe. I need to get some new socks before I lose a toenail.
