look up any word, like blumpkin:

When you are banned from posting in Yelp threads for violating terms of service you are said to go to Yitmo. Yitmo is a play on the word Gitmo, or Guantanamo Bay where prisoners are detained outside the US without due process.
When I posted links to my GF's nude pics, I got yitmo'd.

That guy who was posting about how to get a date with a prostitute is in Yitmo.
