a suspicious character who is high on crack-cocaine with long skinny fingers and long fingernails. a nahkla can also be known as a butt-pirate in the night. if you feel pain in your ass in the morning, you may have been visited by... the nahkla.
Last night i had a nightmare. I woke up and found a trail of blood from my anus. There was shit stains on my bed. The Nahkla had been here.
