NFO

I just came up with this abbreviation for this purpose.

NFO: "Now Fuck Off"

This is what you put at the end of an email, forum post, or other written correspondence to say the words, without actually coming out and saying them. Especially to those who have no clue.

"Oh yeah...great job on kissing the bosses ass in the meeting. NFO"
