Habajakk
A Habajakk is a person who’s crazy but still knows what they're doing. They don’t like being told what to do and love being a troublemaker.
That Habajakk once started a snowball fight in the middle of a math test.
My uncle is a Habajakk. He once ran a marathon in pajamas and a hat.
The Habajakk in our class once tried to talk to a pigeon and got into a debate.
