Anyone who isn't new will probably know about this. If not, this is a term to describe how effortless a pvp fight was. Most of the time, it's them been cheeky about it, thinking that they're so good that it was easy, hence the common stock phrase on Mineplex and other servers. As you might expect, this phrase is somewhat disrespectful to those who lose, even if neither side had the upper hand. Now choosing to actually blacklist this is totally up to you, though it would clean the chat a slight bit.
