Twatluck

Very similar to a potluck, a twatluck requires every man attending to bring not a dish of food, but an attractive and sexually indiscriminant female. The beauty of the twatluck is that if planning a party or trip, you can easily tempt the woman to join if she isn't pressured to sleep with you; however, once on the trip (if the twatluck if successfully carried out by all male members), you will have a perfect guy-to-girl ratio with ample amounts of easy women.
