When a male inbetween the ages of 75 and 95 masturbates so hard the skin on his penis slowly starts to come off but because the male is so old it does not come off normally but rather falls off and turns into small little dandruff like flakes known as dick dust.
Oh shoot! I gotta go sweep up my Dick dust again!
