A person who has undergone decompression surgery to relieve pressure on the brain stem and to allow the cerebral spinal fluid to flow properly. Ususally as a result of trama or a condition known as Arnold Chiari Malformation in which the brain can become herniated down the spinal cord. The resulting scar looks like a zipper up the back of the head.
I went through decompression and I am proud to be a zipperhead.
