Pervert’s Apron
Also known as the soul patch, mouche, or jazz dab, the Pervert’s Apron is a small strip of hair underneath the lip on an otherwise clean shaven face. A moustache is however permitted, which the completes the Pervert’s Apron and Pervert’s Umbrella Combo.
I have gone down a strange internet hole looking at celebrity Pervert’s Aprons.
