I call it Sing n Lose. Well, at least that's what I've got to work with for now. The idea behind this game is to either sing, hum, or just play a song directly for people in earshot to hear and just see if they end up tapping the beat, singing, humming or whistling any bit of it after the song is over.
Now I've been playing this game for years without people knowing about it because I like to think that I've entered their minds and meddled with it, and therefore have the upper hand.
Like Ass Pennies only less gross.

I admit that the game gets more fun when introducing it to others. I don't personally play in order to hit someone on the arm as one does with the 'Circle Game' or 'Punch Dub', formerly named 'Punch Bug' but one could integrate that in the game if they wish. Some of my co-workers refer to this game as getting 'Gooched' because once a person has fallen victim to another person's attempt at getting them to sing a particular song, the winner owes the loser one uppercut to the Perineum.
Luckily no one capitalizes on the opportunity to do so.
The key to this game is that players must adhere the honor system like in The Contest since getting someone could take several hours for the person to react to the song. If you end up singing the song that someone sang near you a couple days before and it can be directly attributed to that moment. Count yourself gooched.
