A nickname for a shirt with a contrasting collar and cuffs, usually a blue shirt with white collar and white cuffs. Lee Iacocca started this fashion trend back in the 80's. This nickname developed as a result of the character Gordan Gecko wearing these types of shirt in the movie Wall Street. These shirts seem to phase in and out of style every few years.
Everyone has a Gecko in the back of their closet.

An awsome little critter that can run up walls and lick it's own eyes.

It is the mascot of Geico and can save you on your car insurance.

However, leopard geckos, the most common pet geckos, cannot stick to walls but have eyelids, something rare among geckos.
WOW! I wish I was a gecko!
