Note: I do not create this addon, it was originally created by Trogdarr for Warriors.
Its a nice addon to have for DK tanking randoms or if you are really angry with the boss mob and feel the need to have Gunny scream at him.
Side-Note: You will likely have to have Load out of date addons turned on for this work, not positive on this since only myself and two others have tested it.
Have fun with it, post comments, I might feel the need to update it with more Gunny sound clips and add Death grip to the taunt list.
Warning: Offensive language contained within this addon.
Disclaimer: I am not responsible for wipes this addon may cause due to the tank laughing or humoring him/herself with this addon.
