A skinny obnoxious person who is starved for attention. Very loud and boisterous with extreme mood swings: one minute they are on a high horse annoying others, and the next the world is ending in their opinion. They tend to "bob" when in high horse mode.
The hernigan that is perched up at the bar is getting on everyones nerves. I wish someone would bring him down off his high horse and send him home.
