Pacific Northwest slang, traditional Puget Sound area, Eastern Washington, Oregon. A party. From Chinook Jargon "potlach", to give, a gift, an event where many gifts were given.

That feeling when you attend an event and have a great time but then when you arrive home and look at social media you get FOMO because you missed so much at the event you attended.
Man I had such an amazing time at the fest this weekend but then ¡boom! massive potlatch when I got home and saw all Jim's photos on Instagram.
