f'darn
a desperate shout you make when you're halfway through saying 'fuck' and you see your teacher like a horror movie villain.
'F'darn!' I yelled as my teacher walked in like she had just escaped from prison.
'F'darn!' I shouted as my teacher stood there with a look that said, 'I will give you a detention.'
'F'darn!' I screamed as my teacher was right behind me like I had broken the rules of the universe.
