I have seen many explanations of this, but here I will explain how it works:
A chav girl has sex with her chav brother, who is also her father which is not uncommon. They produce a chav child, which will biologically be both her brother and her son. At the age of about 8, the chav child will have sex with it's chav mother afore mentioned 'chav girl', producing another child to which the previous chav child will be brother, uncle, and dad.
chav: im gona see ma da tonight.
chav#: e's ur uncle too rite?
chav: yeah an my bro. e's my bruncledad.
