Obviosity
Obviosity is when something happens right in front of you, but someone acts like they just discovered fire, and it's annoying as hell.
You watched your brother get tackled in the football game. He screamed, 'Did you see that?! I got TACKLED!'
You were there when your best friend spilled their juice. They yelled, 'Did you see that?! I spilled my juice!'
You were in the room when your teacher caught you cheating. She said, 'Did you see that?! I caught you cheating!'
