gafgaf - A word you throw at someone when you're too dumb to think of

A word you throw at someone when you're too dumb to think of anything better. It means they look like a disaster or have something strange going on.

'Gafgaf!' my dad said after I tried to paint my face with ketchup and got it all over the kitchen.

My neighbor called me gafgaf because I ran out of my house wearing nothing but socks and a hat.

At the park, a kid yelled 'gafgaf' at me because I was pretending to be a dragon and eating pizza like it was fire.
