i guess that lyk most of our years bullshit this was derived from years of listenin to bollocks jokes, nd waiting in several awkward silences, it was the word "no" extended, and forced to morph until it sounded more insulting,

A:hey "name!" ur gay!
(come back)
B:well, ur mums face is on a billboard doing this, *pulls not so humourous face, in feeble attempt*
A+Everyone nearby: NAOOOOOOOOoooooo....
