Lua is mostly just people using wtf in a l10n var (SoundWTF) or as a variable or something trying to be funny: https://github.com/search?q=wtf+extension%3Alua&

  The answer is in the comments of that site. Lua is used in lots of places, but the earliest "famous" one is World of Warcraft, where it is used to make extensions. The folder where those extensions are stored is called WTF (Warcraft Text File), so on every warcraft extension the string WTF appears multiple times.
