Haggidy
A haggidy is a guy who lives by his own rules. He doesn't care about anyone or anything. If he wants to sit in the middle of the street and stare at a pigeon, he will. He won't even look at you if you walk by.
I saw a haggidy sit on the sidewalk during lunchtime. He just stared at the sky like he was king of the world.
My friend’s dog ran into a haggidy at the park. The haggidy just kept eating his sandwich.
At the mall, a haggidy randomly started doing yoga in the middle of the food court. No one said a word.
