hairstank
Hairstank is the smell your hair makes when it’s been on your head for so long it thinks it's never coming off. It's like your head is a prison and your hair is the smell of the jail.
My hairstank was so bad, my dog ran away.
I took one whiff of my hairstank and I felt like I was going to vomit.
My friend’s hairstank was so bad, it could make a dragon cry.
