G-Zer
a cool old dude who still knows how to party, even if he can’t stand up straight anymore
My grandpa is a G-Zer. He still knows how to dance, even if he can’t do it without a walker.
My uncle is a G-Zer. He still goes to the bar and drinks more than everyone else.
My neighbor is a G-Zer. He still rips up the dance floor at the club.
