Phrygian

someone with a shapely buttocks. This is not meant to be a joke

Believe it or not, callipygian means having "beautifully proportioned buttocks."

The word is derived from the Greek word kallipugos (kalli- meaning beautiful and pugē, meaning buttocks).

"Callipygian" means "to have well-shaped buttocks." Just be sure to spell it correctly, or the compliment may fall flat.

Oops. You've spelled it wrong. It's callipygian.

Believe it or not, it means "having nicely shaped buttocks" so a good use in a sentence might be, "Depending on whether or not you believe that size matters, Nicki Minaj might be considered callipygian."

Feel free to impress some girl or guy at the bar with this one some time.
