LOL No....

it's like a pre wedding reception. Where I am from Brides and grooms to be throw a big party to raise money for their wedding or honeymoon or house or whatever. they sell tickets and rent a hall and a dj and serve booze and have door prizes and there are usually silly games like goldfish races to play. They usually have this party a couple months before the wedding.

I had no idea that this was not a normal thing everywhere lol.
