jackeloff
a person who acts like he’s the smartest person in the room but is just a walking disaster who doesn’t know when to stop talking
Jackeloff tried to fix the internet. He unplugged the router. Now it was broken.
He said he was ‘boss’ then got beaten up by a kid. Still called himself boss.
He tried to make a joke. It was about his hair. No one laughed. He still thought it was funny.
