Ok, Kabaddi.
Kabaddi is a sport like this. There are two teams on either side. Each team has two lines drawn, like this.
Team 1
Team 2
There is about a six-foot gap between each set of two lines, and a large “free” space in the middle.
Each team selects a player by turns. Each player must cross the first line, cross the second line, then cross both back again.
Easy, you say? Well. As long as you are in the “team’s space” - that is, the space in between the two lines, the team has certain things they can do to stop you. They may not hit you or hurt you or tackle you. They can, however grab you bodily, wrap their arms around you, or pile on you.
Not done yet. You also must not take a fresh breath while you do this. So as you cross, you must constantly say a word to prove you are not taking a breath.
The syllable they usually use is “ku” so you hear them saying “ku-ku-ku-ku” the whole time.
Some people rely on speed to get themselves their and back. Others, on their strength, or their deep lungs to be able to last.
And you don’t need to cross it entirely. If they are all piled on you but you stretch and your finger crosses the line, you’re safe.
Ok, so in a country where even now man-woman touching or chaperone-less meeting is considered a bad thing in many places, you can see why co-ed games are considered very naughty and highly taboo.
