Batty Boy means a homosexual --- batty being an anus, hence batty boy means bum boy etc etc.
These people are about in Essex, mostly where we border London. The vast majority of the indigenous population of places like Romford, Ilford etc are all the kids of East Enders or East Enders themselves. As you can imagine, such individuals are treated with the contempt they deserve, especially the white ones. I will say no more on this as it is not the place, but I hope you have learnt something to keep you in good stead, especially as it is Carnival weekend .... I am now signing off init!
Coincidentally, I sent a load of P6 bits off to Australia today .... If East London is anything to go by, the future of this country is bleak, I think I should have wrapped my family and I up too and got in the box.
