One of my cousins who lives in California is gay.
Back when I was a kid (and he was a young adult) my Mom said he was “light in the loafers”.
Not sure if I’ve heard that term anywhere else LOL.
Oh in South Carolina and Coastal Georgia, it’s been used about people for ages, Like Light in the Loafers Lindsey.. or that certain cousin or uncle that you weren’t allowed to be alone with.
