A game you play with people when you are driving. As soon as a person see's a car with three headlights, the person yells three play, and hits the roof with his hand three times. The last person who hits the roof is a mcfaggelwaggel, and has to take off one article of clothing.
Gabe: *hits roof* Three Play!
Riley: *hits roof* Three Play!
Zach: *hits roof* Three Play!
Nathan: *cries and takes off one article of clothing/accessory*
