Wrong way celebration
Score a defensive TD from interceptions or fumble recovery. Celebrate over the top (press Triangle after you reach the end-zone). Take your time even while you are choosing your PAT play. You will see the QB who made the mistake celebrating as if he was the one who threw a TD pass. The wrong way celebration also applies with toned-down celebration (Square) and multi-player (Circle), but the prevalence of the QB celebrating is less often.
