A human who thinks they're funny and keeps trying to prove it by being the worst at everything.

My uncle is a naatmossel. He told a joke about a banana and no one laughed.

My coworker is a naatmossel. He tried to sing and it sounded like a cat was being tortured.

My pet turtle is a naatmossel. It stares at me like I broke the internet.
