If a man is buff, he has a body that is a good shape, and looks as if he has done a lot of exercise:
He was spotted on the beach looking extremely buff.- verb
To rub an object made of metal, wood, or leather in order to make it shine, using a soft, dry cloth- [etc] [Cambridge Dictionary]
I wonder if younger readers know this meaning of buff, seeing as I hadn’t run across it myself in decades. Noted in this Stephen Colbert / Pete Buttigieg half-interview.
Pete continues to impress as a guest.
