Indian version is corrupted, anyways the Indian version has to do with Piss drops falling on your trousers if they are longer than your ankles, and with piss being najis .... and it is for this reason alone that Indian muslim males squat to pee

Call me thick, but dont get how you are more likely to get pee on your trousers if they are an extra inch in length? I reckon it must be something to do with stopping interest in latest fashions, or trouser-ends being in contact with dirt on the floor?
I still prefer Berbs angle - the arrogant display of wealth.
Todays flashy BMW driving, gold-tooth inlayed, micro-thin mobile phone carrying, bling-wearing chavs had nothing on the exuberance of those extra-inch trousered show-offs.
