O-skeezy
An O-skeezy is a person who raps so good, your brain short-circuits and your mom calls the cops.
That O-skeezy just made me drop my lunch and start crying in math class.
My little brother is an O-skeezy. He raps so good, my dog started barking rhymes and my sister started dancing.
He rapped so hard, my teacher started grading my test with a beat.
