What is "champissage"

n. (context trademark English) A form of Indian head massage, supposed to release pent-up negative energies.

Champissage (a trademark; possibly a portmanteau of chāmpi, the Hindi and Urdu term for the practice, and massage), also known as Indian head massage, is an alternative medicine massage. In champissage, the head, neck and face are massaged. Indian head massage was brought to the west by Narendra Mehta in the 1970s. Champissage is thought to have been originally introduced into the United Kingdom by Garaldeep McCoy, an Indian immigrant of Scottish ancestry.
