Just a quicky: I found the following while wandering around the WotLK leaks wiki page for uncategorised spells.
51663 Slap to the Face Delivers a face slap to all nearby players, stunning them. Targets affected by this ability can still communicate through the forums. Lasts until the next patch is released.
For some reason, I have a funny feeling that's not going to make it live...
Ninja edit: there's something absolutely hilarious down the bottom of the page regarding Nesingwary. I decided not to post it here verbatim, as some might prefer not to see it. From what I can tell, it's apparently something you would get in the mail. Click the link above, head to the bottom, and have a look. I lol'ed.
