A potluck is a communal gathering where each guest or group contributes a different, often homemade, dish of food to be shared.
Other names for a "potluck" include: potluck dinner, pitch-in, shared lunch, spread, faith supper, carry-in dinner, [1] covered-dish-supper, [2] fuddle, Jacob's Join, [3] bring a plate, [4] pot-providence and fellowship meal.
The first known use of the term is from the late 16th century, likely from the words pot and luck. [5]
Potluck dinners are events where attendees bring a dish to a meal. [6] The only traditional rule is that each dish be large enough to be shared among a good portion of the anticipated guests. Guests may bring in any form of food, ranging from the main course to desserts. [7]
