"In marketing language, a gimmick is a unique or quirky special feature that makes something "stand out" from its contemporaries."
A gimmick is a gimmick even if its based off real life. You dont need to have an over the
top gimmick like Doinks for it to be a "gimmick." I like that people base their gimmicks off their real life personalities because if they didnt we would have a bunch of Doinks and Undertakers running around. It would become far too cartoonish.
