A Dirty Mustache
A Dirty Teen Mustache is when a kid shaves his face and tries to grow a mustache, but it looks like he got hit by a bad haircut and a bad idea.
That kid’s mustache is like a failed attempt to look cool.
He looks like he tried to grow a mustache and got rejected by the mustache gods.
That mustache is so bad, it makes his face look like a mess.
