naggerz
Naggerz is a shoe-stealing monster from World of Warcraft who follows people around and yells at them for being weak.
Naggerz stole my boots mid-boss fight. I died. He laughed.
I saw Naggerz in the lobby. He had my shoes. I had no shoes. I cried.
My friend got naggered by Naggerz. He lost his armor. He got banned.
