In La Habana it's commonplace to see or better yet hear a man whisper a "piropo" as a woman walks by him.
"If beauty were a sin, you’d never be forgiven."
"I’m now sure there is a heaven because I’ve seen an angel."
"Oh! If you could cook like you walk, I want to eat scraps!"
"So many curves, and me without brakes."
Pi-ro-po \pi-‘ro-po\n. pl-pos [Sp. Piropear]1. An amorous compliment 2: A flirtatious remark.
