Macoon
Macooning is when you try to trick someone with a dumb joke or lie. You don't get away with it, but you still think you're cool. People call you out for being a f***ing idiot.
My friend tried to macoon me with a joke about cows. I saw through it and laughed at him.
At lunch, I macooned my brother with a fake story about aliens. He fell for it and cried.
My teacher macooned the class with a fake pop quiz. We all screamed.
