> What you're describing verbatim is a potluck. Potlucks in the US are popular among immigrant groups, family friend groups, or parties for clubs or associations. But ultimately they're considered a bit uncool/laidback and don't fit the definition of an American party. They're better described as "get-togethers".

As a foodie in the Pacific Northwest I disagree with this statement.

Potlucks are a chance for people to show off their skills. Some of the best potlucks I've been to have a competition aspect to them, complete with prizes.

As a host of a potluck I'll handle drinks, entertainment, and renting a venue, but the guest list is around 80% people who I can rely on to cook a damn good dish.
