La. A common term used throughout the chav world. But at this present moment in Gods great world, emo's and goth's are starting to use the word 'la'. I think this is a discrete and clever way in taki the piss out of the mummy boy chavs (You fuckin gays).
N.B. (You may elaborate upon the 'a's you use for an even more dramatic effect.)
Damien - Alrite la
Tom - Hi hunni
Damien - Chavs are gay as fuck, wudnt you agree? Laaaaa <<<(Elaborated a's)
Tom - Yes, 100% and with feeling, they are poo pushers to say the least.
Damien - Hmmm i wonder how an emo chav wud speak...
Tom - 'Ii Luff Yoo Laaaaa xXx <3333333'
