buttcrack in public

When I finished work, I went for a walk in a park with five inches of my butt crack showing; I wanted to grab my phone to take a picture, but it slipped out of my hands. Sighing, I squatted down, exposing ten inches of my crack to everyone passing behind me. A few people saw it and laughed, and someone else came over to tell me it was showing; I was embarrassed in the moment, but I thanked them and pulled up my pants.
