Sheriff of town nowhere

A person who plays "Sheriff" over something insignificant or otherwise not worth the time. Usually in small groups of people they like to take control and power over a situation that doesnt need authority or want it.

Person 1: I was in this Group Chat with this guy and he was contantly telling me what "rules" i needed to follow. Hes genuinely playing Sheriff of town nowhere.

Person 2: I was in a discord server in a dead community and this guy was still moderating the server and telling me

what to do when nobody has spoken on it in 4 months! He must be a fat loser and need to be a Sheriff of town nowhere in order to satisfy his power complex.
