end of a 3 day climbing trip and we wanted to burn out on our last day so we climbed some routes a little below our grade, We were 5 routes in and i was doing this little arete and somehow i managed to clip in above me , then somehow the rope clipped itself again below me. So it ran up, back down then back up to me. I downclimbed and unclipped it only to have the rope knot below my belays atc. so i had to clip into a hanger while he went off belay and untied the knot. It was a clusterfuck.
