face ruiner
A face-ruiner is when one part of your face is so bad it makes the whole thing look like it was dragged through mud, even if the rest of you is perfect.
My nose is like a broken traffic light, and my face is the muddy mess.
My ears look like they were ripped from a donkey, and my face is the trail of destruction.
My eyebrows are like two angry raccoons, and my face is the forest they destroyed.
