I don't get it, but I saw Avatar, so I upvoted.
I was in a game where someone on the enemy team got annoyed with our salty top laner so he started acting like he misheard somthing. We knew he didn't Couldn't but laughed as our top laner fell right for it and kept trying to emphasis what he was saying. Thanks for the upvote, but it feels, empty, when no one gets the joke
