jackface
A face so ugly it looks like it was drawn by a kid who hasn't touched a crayon in 10 years.
"Look at his face, it's like a jackface.", said by a kid who was stuck with a classmate for a project.
"He made a jackface when he failed the test.", said by a kid who passed the test.
"That's the most jackface I've ever seen.", said by a kid who was actually the one making the face.
