Haggard Douche - A man who looks like he hasn't washed his hair since the din

A man who looks like he hasn't washed his hair since the dinosaurs roamed the earth and probably still smells like one.

My cousin's ex is a haggard douche. He once tried to flirt with me while wearing the same shirt for a week.

I saw a haggard douche at the grocery store. He had a beard like a raccoon and was eating a bag of chips out of a sock.

My teacher called my friend a haggard douche because he showed up to class with a face full of pizza grease and a hairball.
