Ah yes, the good old fashioned b*tch-slap. Not that I have ever had to resort to it, but I do believe it is more humiliating to get slapped than punched in the face... I would rather keep my teeth intact to be honest!
I have never had any problems with "yooves" on their own. They generally look at their feet. Even in gangs they seem to see a guy in his twenties as an "older boy" rather than a grown up, so we get left alone. Only time I have ever had any problems was with... wait for it... girls! Seriously. I was walking along a street through a rough part of town in the wee hours. Two girls (I would reckon 15yo) walking towards me on the pavement, so at a distance away I moved over to the left of the pavement. So they moved over to my left. I moved over to the right, so did they. Both looking pretty shifty, so I made a cursory glance to make sure their hands were empty (didn't want to get stabbed). One of them barged into me... I found out that evening that 8 stone girls have a tendency to bounce off 16+ stone guys.
After picking herself off the floor, they just carried on until they were at a safe distance, then started hurling abuse. Unfortunately I couldn't think of anything "street" to say and based my rebuttal on the fact that for ME to move out of HER way would require a greater change in momentum
Although it had the desired effect, they looked a bit confused and said no more.
My ex and her dad were having problems with some yobs who were kicking footballs against their (and everyone else's) cars. So I took their football, was a good leather one too. Can you tell that 60% of my family are teachers?
Gave the ball to some kids who were looking bored in the park next to my mate's house (in a different town), hopefully they didn't cause any trouble with it!
