Confetti is the small pieces of coloured paper thrown at a celebration. Weddings mostly, and it gets everywhere.
It is a mass noun with no plural, so you throw confetti rather than confettis. Many churches and venues now ban paper and allow only dried petals, which biodegrade. The word is Italian and originally meant sweets, which is what was thrown at carnivals before paper took over. English has a vivid image in torn to confetti, meaning shredded into tiny pieces.

confetti
Borrowed (possibly via French) from Italian confetto literally “confections”, used to describe sugar-coated almonds, and by extension things imitating them (like pellets of plaster), which were thrown in Italy during festivities like Carnival and weddings. (This practice is mentioned in English since at least the 1810s.) The French and the English adopted the practice of celebrating weddings and other festivities by throwing such candies, or (by the late 1800s) tiny pieces of colored paper symbolizing them, partially displacing their earlier practice of throwing rice.
