A thick encrusted layer of fecal particles that has dried and hardened and somewhat fused with the skin of the buttocks. It results from smearing butt excrement when whiping rather than actually removing it. As it hardens it becomes brittle and starts to crack, then small particles of the fecal-layer waft into the air and can get lodged in people's nostrils or open wounds, causing severe irritation, runny noses and gagging.
Man, Mandy is such trailer trash. I did her doggy style even though her whole butt was encrusted with buttflakes. Each thrust i drilled into her shook off more buttflakes, creating a thick green mist of butt flakes, and I gagged.

Man, Mandy is such a slut. I was gonna do her doggy style but her whole butt was encrusted with buttflakes.

Man, I went to a gay bar last night but i couldn't breathe cuz the air had a visible mist of brown buttflakes.
