Backdoor
Pushing or attacking enemy turrets while the enemy team is occupied elsewhere.
Backdooring means attacking the enemy base or turrets while their team is grouped somewhere else on the map — contesting Lord, fighting your team, or pushing your side. A split-pusher like Yin or a wave-clearing fighter can solo a turret in the seconds it takes the enemy to realize their base is undefended. It's high-risk, high-reward: if the enemy rotates back before the structure falls, the backdooring hero is usually caught alone and killed.
