Apparently, interfering with a player on the MSI stage is known as a "fan gank"

Was looking at the rules for the MSI, and this jumped out at me. And caused some giggles.

Player Pause. Players may only pause a match immediately following any of the events described below, but must signal an MSI official immediately after the pause and identify the reason. Acceptable reasons include:

• An Unintentional Disconnection
• A hardware or software malfunction (e.g. monitor power or peripheral disability or game glitch)
• Physical interference with a player (e.g., fan gank or broken chair)

The area around the stage is pretty well warded, though. [sg-lulu]
