To be a Chav is to be one of the most base forms of mamalian life on this planet thus chav watching is akin to observing a single celled organism in a petree dish.
Chav watching envolves going to a McDonalds, sporting goods shop or for the more fool-hardy chav spotter a council estate and observing these strange devolved heaps of puss going about thier day to day lives (if you could call their existance a life).
A word of warning if chav watching on a council estate and you spot a group of 8 or more chavs you will be lucky to leave with all 4 limbs.
Guy No 2: I'm going Chav watching
Guy No 1: Holy shit dude are you going with an armed escort?
Guy No 1: No
Guy No 2: Are you at least taking a small amount of naplam with you?
Guy no 1: No
Guy No 2: Rather you than me!
