Some of my friends are engaged in an outdoor game in urban streets with other couples but, because I am single, will not let me in on it - it is considered to be for participants only.

It is called "sneaking" and sounds exciting from those who take part.

My friends say: "Get a partner and you can play with us."

Can anyone break the silence and tell about this game?
