How can i get my rep back?

a few days ago i was hanging out with my friends and there was a really hot chick that i was going to ask out so i got her and we were alone in some alley and i noticed my stomach hurt but i figured it was just the nervousness so i was just about to ask her when some kid rode by on a bike and hit a pothole and face-planted l laughed as hard as ever and then i **** my pants and it was right in front of her i was so embarred and she went and told everyone about it and now i have no friends
