Why do people throw confetti’s in Weddings?

Confetti’s everywhere in big events? Why, why in big events such as a big sport event, a world cup and a wedding why do we use it, ok we use to make the events more spectacular and the victory more sweeter. The main goal of weddings were to produce children so the crowd would throw symbols of fertility such as wheat grains. The Romans took it a bit further with, they baked the wheat into cakes for the couple. They were to be eaten together and the tradition was known as conferriatio which means eating together. After that cake eating moment, the guests would throw honeyed nuts and dry fruits at the couple, this is where we got our tradition of throwing confettis.
