A hypothetical game that is played by placing the thumb of one's hand into one's own mouth while simultaneously placing the thumb on one's other hand into one's own anus, and then switching the thumb positions after an undetermined period of time. Most commonly used as a term to negatively express the passing of time with extreme inactivity or waiting. Very similar to the term "Grab Ass".
John: "Did you have a date with that girl last night?"
Tom: "Nah man, she said she'd call me back in 10 minutes but never did. I sat around the house playing 'switch-it' all night."
