Is the word “chuunibyou” originated from the anime Chuuni?

I was reading Black Lagoon and realized that Lotton is a bit like chuunibyou. He called himself "The Wizard" and he always wanted to make a cool entrance before a fight but usually get his ass kicked quickly. In my opinion, he's a chuuninbyou. But no one ever mention that he's chuunibyou.

(Or probably he's not chuunibyou after all, but keep that for another question)

Being the earlier anime (Black Lagoon was aired in 2006 while chuuni was aired in 2012) it got me thinking if the word chuunibyou was actually originated from this anime. Or probably it was not just as popular as now.
