HAFFA
A weird math problem that only a haffa blowie would understand, like your brain is broken and your head is too big.
He said, ‘Haffa blowie’ after trying to do math and failing, like his head was a calculator and it was broken.
She did the haffa blowie equation and ended up with a headache and a bad math grade.
He tried to explain haffa blowie and it took 10 minutes and 3 bad jokes.
