Sticky residue, also know as semen, left above the upper lip of the person who just gave a blow job. The semen dries to give the appearance of a white mustache. Got cum?

After the act of oral sex, on occasion the partner's cum is left behind on the upper lip, under the nose. This can resemble a mustache and commonly confused as a milk mustache.
