I don't think I'll be using this name. I think this should be a Troll shaman's name, but I am going ally not horde (I know, gross, my friends are going ally). If you are seriously trying to get it, contact me!

A guy on the Classic WoW subreddit made a post asking people what name they were going to reserve and he made the unfortunate mistake of saying the name he'd be reserving: Thex.

The Scarab Gong looms ominously before you. Steel yourself, adventurer; for once the Scarab Gong is rung, the gates of Ahn'Qiraj will be opened.
From the slackened maw of the beast can only come chaos and destruction. Defend your people!

Some well-known player started a thread on Reddit asking everyone what race/class they were making and what their name would be. He naively mentioned his own name Thex, not thinking it might get ninja'd, and the internet ran with it.
EDIT: What Herrington said.



A person in their hype waiting for Classic, made a thread on reddit saying how excited they are and will be rolling a troll shaman named 'Thex.'
Of course, in their hype, they forgot that telling what your character name will be to many people, will result in people going to take it just because the hell of it.
So, it's nothing special, or anything unique, just a person who made a mistake in their hype thread.
