gafgaf
A stupid word you shout at someone when you're too dumb to think of anything else. It means they look like a mess or have something weird going on down there.
'Gafgaf!' I yelled at my cousin after he ate three tacos and started dancing in the middle of the grocery store.
'Why did you call me gafgaf?' I asked my friend. 'Because you looked like a confused raccoon wearing a hat made of pizza.'
My teacher called me gafgaf because I fell out of my chair and started screaming about aliens.
