A stengoat
When someone has a total meltdown and needs everyone to notice them. They leave groups or pick on one person until they're the only one who matters. Usually happens to short guys with low IQ and a bad GPA.
Text: 'You all are stupid. I'm going to leave this group and tell my mom about this.'
In a group chat: 'Why are you all ignoring me? I'm going to scream at Mike until he cries.'
DM: 'You're all losers. I'm the best one here. I'm going to text my brother about this.'
