Dumugian

A Dumugian is a person who spams a lot on the internet and doesn't know how to read the room in a social situation. The Dumugians become obsessed with a subject or a person and they'll spam all over the internet or stalk the person.

A dumugian will also mass tag people or spam posts on social media, arguing with people in a way that makes no sense.

Another aspect of a dumugian is stalking and harassing people or naming random people as if everyone should know who they are.

i even had to delete some of his messages because he kept interrupting me and tagging me while i was writing, he picks one detail of what i write, distorts, misinterprets it, and asks questions about it, you dont even know where to start to answer it.
And this has been going on for hours, so at one point i said i'm tired of it, and that he reminded me of Dumugian.

This guy spammed the whole subreddit with political nonsense, i bet he's dumugian.

Dumugian, stop tagging and harassing me! Stop making random accounts to DM me!
