A term declaring the nineties to be the first decade in which men could show their sensitive side and become sensitive new age guys. Referring to someone as a nineties man suggests that they are the type of guy who is not afraid to order quiche in a restaurant or cry at a movie. This evolved into the term metrosexual, a man with an excessive grooming routine, or who manscapes.
"Hey, I'm a nineties man." or "Remember when everyone used to say 'Hey, I'm a nineties man?'"
