moustache
also referred to as smearing. gathering up a finger or two full of that nasty greeze that forms between the upper inner thigh and scrotum, after a day or two (or more) of not showering, and then wiping or rubbing the finger(s) across the victim's upper lip area, directly under their nose, so as to cause them to have to smell the foul substance.
I gave that dirty bitch a moustache she'll not soon forget.
