hairstank
Hairstank is the smell of your hair after it's been sitting on your head like a dirty sock. It's a mix of gunk, sweat, and old conditioner that could make a vampire gag.
My hairstank was so bad, my teacher moved me to the back of the room.
I walked into my brother’s room and his hairstank was like a fart storm.
My hairstank could make a ghost run away.
