Minions BM an enemy team with emotes and leave one League player puzzled

One League of Legends player on the Japanese client recently noticed that their minions did something different than usual after they aced the enemy team.

Imagine getting aced by the enemy team, but as you’re getting aced and are at the gy screen, you see your enemies’ minions add to the BM with emotes celebting your death. Well, one League player recently saw this happen.
