Chocoholic

A chocoholic is a person who craves or compulsively consumes chocolate. There is some medical evidence to support the existence of actual addiction to chocolate. However, the term is mostly used loosely or humorously to describe a person who is inordinately fond of chocolate. The word chocoholic was first used in 1968 according to Merriam-Webster. It is a portmanteau of "chocolate" and "alcoholic".
