1. An offensive term to tell someone to go away

Go away!!!!!!!!!!! AND LEAVE ME ALONE!!!!

"Fuck off." It's such a lovely pair of words! And it's international. I don't care where you are - if somebody's fuckin' with your bags in Lhasa Airport in Tibet and he's got a shaven head and saffron clothes on and you say "hey, fuck off!", he knows *exactly* what you mean. Exact - he will fuck off. Off he will fuck! 'Fuck off' doesn't mean 'go away.' 'Fuck off' means 'fuck... *off.*' And everybody feels what it means, nobody can write it down. There is no English equivalent for 'fuck off,' because... it *is* English, 'fuck off.' You know? And English expressions don't have English equivalents, they fuckin' *are*, ya know?
