Howl Of Terror is a move in the game " WORLD OF WARCRAFT" for Warlocks. When you cast Howl of terror everyone around you within ten yards are flee'd in fear of you.
IRL howl of terror (in real life howl of terror) is what I wish I had at concerts when I am stuck in a mosh pitt..
Shit, this mosh pitt sucks. I wish I had IRL howl of terror.
