kaa karrrr
A loud, messy noise you make when you're too dumb to do your job and your brain is melting like a burnt marshmallow.
'KAA KARRR!' I yelled at my computer. It didn't respond. I got fired.
'KAA KARRR!' I howled in the breakroom. The coffee machine exploded. I got a raise.
'KAA KARRR!' I screamed at my printer. It printed 'you are stupid' in big letters. I cried.
