k-deeldo
A k-deeldo is a person who acts like a brain-dead donkey. They either mess up or do something so dumb it makes your face turn red.
My cousin ate a whole pie for breakfast and then called me a k-deeldo.
My teacher said, 'K-deeldo!' when my dog barked during the math test.
My dad yelled, 'K-deeldo!' because I wore socks with sandals to school.
