look up any word, like hipster:
 
1.
Shaving at a point in puberty where proper facial fair is yet to develop, only 'bum fluff' however it is still necessary to shave to remove this 'hair'. As it is not a proper shave it can only be refered to as facial dousting as all the fluff and dust like hair on your face is being removed, hence the phrase facial dusting.
