Pabobo
A person who acts like they know everything but then they start talking nonsense and you just want to throw them out the window.
My uncle is a pabobo, he told me the ocean was made of soda and then tried to drink it.
My friend is a pabobo because he said the clouds were made of cookies and then tried to eat them.
My brother is a pabobo because he said the TV was alive and it started screaming at him.
