Top Definition
usage (noun)
A title claimed by many have-been hollywood types, wannabe doctors, and your regular garden variety hollywood "fitness" guru. There is no legal definition therefore allowing any charlatan to use it. Normally used to imply that the person has some knowledge on the science of biochemical reactions which occur in energy expenditure and metabolism as an organism converts food into usable energy-but notice they never use R.D. after their name, as they would be prosecuted for impersonating real scientists.
"Are you a nutritionist?"

That girl Megan was so hot in high school. Too bad she's such a nutritionist. Really let herself go.
