Them gals you see around with a bit of a rough edge to them, but you would still give your little finger to shag them once and then fuck them off. You will see plenty around festivals wearing there air max, in them tight legging with loads of makeup and shit brows and worst of all a gaping fanny (but you won't know that till you know). Once you've nailed that DB all the bros will tell you they rate you and might possibly drop the DB chant x

Dirty bitches dirty dirty birches

I just wanna shag that DB
