...this is a good insult, generally if I say this to people they end up pregnant. Even the men? Especially the men!
On a serious note this particular "go fuck yourself" is directed at a specific individual. Let's call her; a cunt. She has angered me not only because she exists in my world as a rather unattractive oxygen thief and all round waste of skin but also because she adminstered a particularly unneccessary and uprovoked drive-by venom spitting at me, the old 'insult-and-run'. The fatwa has been declared and my warriors have been prepped for battle...I can't be a hero without a nemesis.
Go fuck yourself sweetheart, no one else will.
