It stands for "INTentional feeding" and it is used in videogames (mainly League of Legends).

Most possibly started from the League of Legends banned toxic streamer tyler1 because of his ''INT list'' where he was writing down players who were playing bad, intentionally feed, intentionally ruin the game and so on.

Another case would be from his famous ''Running it down mid'' where he runs down the midlane (as the phrase says) and suicides, giving free kills to the enemy team after getting frustrated about a certain event/player in the match he is playing.

The definition of Inting: To intentionally put yourself or group of friends behind by doing something incredibly stupid or out of anger

Inting in referance to the statement "Intentionally feeding". The word comes from the popular video game "league of legends" where feeding is giving away your characters life to forward the enemy, thus putting you behind.

The word can apply to world outside of league of legends by using it to describe idiotic behaviour of peers when it seems almost too stupid to be an accident.
