This happened to me (the shorts snag but not mooning!) on a metric when I was remounting my bike in a rest stop parking lot. It actually threw me off balance to the point that I went right down on my side since I couldn't get clipped out in time. I was an experienced cyclist and experienced with clipless pedals as well so had never had this happen before. I surely felt sheepish after that - especially since a lot of other cyclists at the rest stop witnessed it!
