1. the top of a man's penis, or a hermaphodite's penis I guess as well. Also reffered to as a purple helmet.
2. A condom, as worn on the head of your penis, perhaps a more accurate term.
3. A kevlar, or plastic covering for your less important head, as worn while riding a motorcycle or visiting a construction site. Or oddly, enough, while exploring actual caverns. See spelunking.

To play the game of Helmet means to touch everything with the tip of your penis. i.e. - to go up to your friend's toothbrush and rub your penis tip on it. Gross? Yes. Amusing? Not really.
