Fabedaf is a word that sounds cool but means nothing and usually makes people yell at you.

My teacher said, 'You didn’t do your homework, fabedaf!' I asked, 'What’s fabedaf?'

I texted my friend, 'Hey, fabedaf!' He replied, 'What is that?'

My friend said, 'I got a job, fabedaf!' I said, 'That’s not a real word!'
