Momo

A highly inexperienced solo chambers of xeric raider on the MMORPG "oldschool runescape". It does not matter how much time he invests, he will not make any progress. In fact, he will get worse and worse as time goes by.

Player 1: Bro, this guy has been solo raiding for over 6 years and he raids like me on my first solo raid. He is so ass.
Player2: Yea, that's a typical momo.
