Hemi is a term used to describe something that is HALF in front. It is derived from the Greek word 'hemi' which means 'HALF'. The term is commonly used to describe a car or truck that has a split front end, with one side being longer than the other. It is also used to describe a person who has one side of their body larger than the other. In both cases, the object or person is said to be 'HALF in front'.
