In professional StarCraft gaming when a player admits his defeat he types GG (Good game) as sort of a "I surrender" and then he leaves the game.
So when commentating on a StarCraft game the commentators often say that the players "type out" when they type GG and leaves.
*FBH types GG and leaves*
"...And he types out! Savior takes this game. GG, good game yall! Looking forward to game 4. Nice type out."
