I have seen chavs this way do it as well.
I was walking along and saw two chavs come by, it was a relativley hot day so they didn't have shirts/t-shirts on typically...
Anyways, couldn't help but see that one of them was at least elbow deep down his "tracky B's" with the other hand holding a cig. It wasn't just for a quick itch/scratch/readjust either, as he was like it from about 50-100yrds away and was continuing after I saw him walk past me. It's like he had some inane reason to just hold onto it for comfort.
It really does defy belief and I comepletley know what Orange Peel means when it's down to generally being a scrote of society and not having any decency, morals or idea of how to behave correctly.
This thread has also reminded me of someone who posted saying they saw a chav man/woman walking down the street coming out of asda or something similar in broad daylight...she had her hand down his trousers and appeared to be tugging merrily away as they walked through the shopping precinct.
WTF?
