mad scratch
A drawing that’s so bad it makes you question your entire life and why you ever picked up a pencil.
His mad scratch of a sun looked like it had been drawn by a man who had just been fired.
I drew a mad scratch of a car that looked like it had been hit by a tornado and a crayon.
My teacher said my mad scratch looked like it had been done by a kid who had just been kicked out of a crayon factory.
