Typographical error of "go," it has now achieved near-meme status for certain internet users.

It originated on on June 2, 2008. Popular and regular member "shaunofthedead" purported to have the opportunity of an orgy with some unknown people. After drunkenly deliberating for several hours whether or not he should take advantage of this opportunity, at 10:42:57 EST he posted simply "fuck it im foing."

He was never heard from again.
"fuck it im foing"
