You're Lucio.
You reach the final point you need to defend just as all your teammates die from an ult. But instead of standing on the point while they respawn, you stand ten inches away from it and start shooting at the remaining enemies on the point. The countdown timer is running out and your teammates are screaming "WHAT THE FUCK ARE YOU DOING?" You ignore them and don't even try to touch the point. Just before all your allies can get back at the same time, the enemies cap the last point and you all lose.
