look up any word, like half chub:
 
1.
1) Rating of a film of the same height of entertainment as James Cameron's massive blockbuster Avatar.

2) Rating of a film that matches or surpasses Avatar financially. Considering there may be a long time until another film to reach the $2 million mark worldwide, a film that can be that successful can then truly be described as "Avatar good".

3) Can also refer to a film that an individual deems as great as Avatar but did not have as great of a financial success. See also The Hurt Locker.

4) Can be used sarcastically by critics and those not fans of Avatar that claim it contained poor acting and just good special effects, to relate to other films of a similar nature. Could also be termed "Avatar bad"
"I hear this movie isn't just good. It's Avatar good!"

"That last show wasn't Avatar good. It was just okay."

Used in alternate sense:

"This movie wasn't really up there. I'd say it was just Avatar good."
