Abbreviation for the TV show Avatar: The Last Airbender. Also written
ATLA or
AtLA. An incorrect and unacceptable way of abbreviating the title would be ATLAB. The B is added by the
ignoramuses of the fandom who don't realize that 'Airbender' is ONE WORD.
Writing A:TLA instead of the full
title saves a lot of time when texting you're friends to
alert them that the show is starting.
