Lip had invited you to Karen's engagement party with him, only there was a catch. He hadn't exactly been invited himself, but he wanted to crash it since Karen broke his heart and fucked his dad frank. You were merely there so Lip could try to make Karen jealous, which was okay with you because you and Lip had been FWB since Karen stopped being his and wanted to get serious with her fiance. Lip and you walked into the party and you saw Karen immediately look over with a pissed look at Lip.
