pot luck
1. A situation or circumstance in which the outcome is uncertain but where one takes a chance in the hopes of achieving a fortunate or beneficial end result. (Used especially in the phrase "take pot luck.") I like to just take pot luck when I travel to new cities and try out whatever local establishments I happen upon. I love going into old antique stores. I know finding something worthwhile is just a bit of pot luck, but it's fun to see all the old things they have!
2. (More often "potluck.") A shared meal in which separate dishes are prepared and/or brought by different individuals; the food that is brought to such a meal. Primarily heard in US. Sarah and I are hosting a pot luck this Saturday, and you are both welcome to join us! Just bring something that we can all share! Potluck dinners are a great way for neighbors or groups of friends to spend time together or get to know each other better. We're just asking guests to bring a bit of pot-luck, nothing fancy!
