Is there a name for KR server style mid game skirmish ?

So if you watch KR server challenger replays, you obviously seen a ton of clips where, one person ganks mid, and within 10 seconds... everyone is in the fight. When its like 10 min into the game. Is there a name for such gangbanging skirmishes?

Like literally example of what happening is maybe, nami support roams mid, enemy leesin ward jumps in 2 seconds later, followed with some allied thresh lanterning another guy, with double top lane TP from both team, and reksai ults mid, etc etc... everyone is just always ready to join a fight. You dont see these a lot in NA.
