The OG "spill the tea" session, but with a priest and it's about your sins. It's the spiritual equivalent of clearing your browser history. You go into a small box, tell the priest your mga kasalanan (like judging your neighbor's karaoke skills), say a few prayers as penance, and come out with a clean slate. Also used non-religiously when you finally admit to your friend that you were the one who ate their leftover pizza.
