Professional wrestling match types
Battle Royal is a multi-competitor match type in which wrestlers are eliminated until only one is left. Typical battle royals begin with 20 or more participants in the ring all at the same time, who are then eliminated by being thrown over the top rope and having both feet touch the venue floor (this is sometimes referred to as the "Shawn Michaels rule", due to the 1995 Royal Rumble, in which he was thrown over the top rope, hung on to the top rope and only had one foot land on the floor). A variation known as the "Reverse battle royal" existed in TNA.
