EatIt is a humorous addon that I wrote for my Worgen toons, although it would probably go well with an Undead toon as well. There's nothing, other than good taste, to prevent you from using it with any toon though.
What it does is do a random emote about your toon either eating or wanting to eat your target. The emotes are different depending on if your target is a player or an NPC, if a player, on whether they are dead or alive and if an NPC, what kind of mob they are. Pronouns of the proper gender are used.
As an example, if WolfGuy were to target his gnome party member, LittleGuy, who is alive, and click his EatIt macro button, you might see something like this:
WolfGuy looks at LittleGuy and licks his lips. Mmm... Gnome Soup!"
Or if WolfGirl were to target her gnome party member, LittleGuy, who is now dead, and click her EatIt macro button, you might see something like this:
WolfGirl wonders if anyone will notice if she nibbles LittleGuy a bit before they resurrect him.
Or, targeting a dead dungeon mob:
Wolfgirl cuts a piece off of Ancient Guardian and chews it slowly. Mmmmm smokey!
There are 4-6 different emotes for each creature type in the game. Some of them are the same. There is no in game config. If you want to include your own emotes, see the remarks in the localization.lua file. (If you come up with any good ones, send them to me!)
