Combination of "Terrible" and "Bad".
Adopted by and, thoroughly beaten to
death, by the shittier World of Warcraft playing community for people that they
don't like. Because every
society of caustic for the sake of cool, self loathing nerds needs to have their own memes and slang to fit in, WoW has this weak shit.
People who realize that "thinking" isn't their particular strength and figure that, being witless, meme sheepish tools, an Armory check and some lame
ass slang should be a good enough replacement for tact, knowledge, facts or well thought out arguments.
Terribad, bads, scrubs,
Futurama references are all ingredients in the gigantic shit
stew that makes WoW players look like the dumbest, most anti-social losers in
Gaming.
