snackluck
n.— «I was encouraged to see so many potluck posts, but I’m wondering—how do you get folks interested in putting out some effort for a potluck, so it doesn’t turn into snackluck (everyone bringing chips or pretzels, with no real food), outside of doing a signup?» —“Baked Chicken Korma & Rice” by JulieR Heeeeeeere’s Jules!
