Obvcourse - A fancy way of saying 'duh' that people use when they think

A fancy way of saying 'duh' that people use when they think they're smarter than everyone else. It's like bragging with a dictionary.

'Obvcourse I passed, I’m the best.'

'Obvcourse you’re wrong, I’m right.'

'Obvcourse the sky is blue, I knew that before you were born.'
