Translation of "Curtan" in English

"Nos ganaron, que se curtan".

"They won against us, have them die!"

Por la noche pongo mis pimientos en la ventana abierta para que se curtan un poco antes de plantarlos afuera, puesto que todavía tienen unos tallos tan finos.

At night, I put my bell pepper plants at the open window, so they can harden off a bit before I plant them outside, cause now they still have such thin stems.
