It's not really a nation wide tradition anymore, but I think kids also did it in other places, before the internet and stuff, and it doesn't really exist now thanks to online hooker directories, but in Calgary, we used to drive up and down the streets frequented by hookers playing a game called Spoons.
You play Spoons with regular steel dinner spoons, the rules of the game are:
Take turns throwing spoons at hookers, if you hit the hooker with your spoon, you win that round, if you miss, you have to get out of the car and retrieve the spoon for the next round.
Many friends almost beaten badly or stabbed, but only lots of fun in the end. For us, anyway...
