One who always ditches, or "flakes," hence the name dandruff; usually for an insufficient reason, getting the hopes up of friends and family and ditching them for materialistic sluts.
Dead skin making a glorious escape from your scalp. A pain in the ass...it makes your head itchy and falls onto clothing (not a good time to be wearing a black shirt).
Some guy: "Dude, your head is snowing. Gross."
Unfortunate victim of dandruff: "Really? Damnit, I need some antidandruff shampoo."
white flaky stuff that comes out from your scalp when either you haven't washed your hair in a while or if you have a dry scalp.
-people might think it's nasty if they see it on someone.
