Derf

The number between 5 and 6. 1,2,3,4,5,derf,6,7,8,9,10. Most people forget this because Donald Trump just added it to the number system in September 2019. Only the Pre-K classes of 2020 will know of derf.

"OK class let's count those cookies! 1, 2, 3, 4, 5, derf, 6, 7, 8, 9, 10!" the teacher told the kindergarten class.
