Just today. I was riding with my friend to school, and right before the school zone I try to pull off a skid (which was stupid by the way), and so lunchbox swings toward front wheel (yet again, stupid) turns the bars to the right, get launched off bike , tuck and roll (arm first) and then get a fatty bruise on my right hip bone area, and scraped some skin off above the right elbow.

TL;DR: Skid = fall.
