Hair Hurt
When you wake up after sleeping with your hair pinned against its natural direction of growth. The result being that the area of scalp where the hair shaft connects ranges from sore to moderately painful, lasting up to a couple of hours after waking. A secondary result is an unkempt appearance to the hair, which no amount of hand-licking and spit-slathering will fix.
I passed-out on the couch with my head against the arm and this morning I have a bad case of hair hurt.
