The peanut butter game is a specific kind of food play where usually a non-feral character will cover their genitals in peanut butter and have a feral dog lick it off. However, this tag is valid for any reference to the "game", including posts that may not feature peanut butter, ferals or dogs.

If you put peanut butter anywhere on your body, he'll lick it off. Anywhere.

The Japanese equivalent is called バター犬 (butter dog), where butter is used instead. The practice of "butter dog" should be tagged as peanut butter game in e621.
