A,D,A,D disorder
When someone in a game is so dumb they type (a,d,a,d,a,d,a,d) nonstop to either ruin the game or prove they are the worst player ever.
He did (a,d,a,d,a,d) the whole game and I got a 2nd place because of him.
She did (a,d,a,d,a,d) and I was like 'why?'.
He said he did (a,d,a,d,a,d) because he was mad at his mom.
