Paarth Diff
The Paarth Diff is when your top laner (usually Darius) beats the enemy top laner so bad, they might as well have quit the game.
Darius killed the enemy top laner before the first minute. Paarth Diff.
Enemy top laner was already dead by level 3. Paarth Diff.
Darius took the enemy tower while they were still in the lane. That’s a Paarth Diff.
