Kusha Las Payas (my bad Spanish)

Good day everyone!
Please help me translate these words or tell by another (Spanish or English) words the chorus of
the song of Las Ketchup "Kusha Las Payas":

Kusha las payas, kusha las payas,
ay qué tremendas que vienen las payas.

Can't understand exactly, guesses only... All rest another I've translated.
Sorry for my english, usually I speak russian
Gracias!
