confeti

confetti

“A los pocos segundos, al levantar Guardado el trofeo, se desató una lluvia de confeti amarillo y fuegos artificiales.” — A few seconds later, as Guardado lifted the trophy, a shower of yellow confetti and fireworks was let loose.

Borrowed from French confetti, and this a pseudo-Italianism, from Italian confetti, plural of confetto (“confection”), reinterpreted as a singular (compare espagueti).
