a.) a cosmetic applied to the lips of a female; usually. Its use was developed in ancient times by prostitutes as form of advertisement, by painting their lips to match the same color as the inner folds of their vagina, so the male customer would get a glimpse of what he was getting. Lipstick was, then, various shades of red and pink. I doubt, if the colors were available, that any prostitute then would have painted their lips brown, black or green, which may have led the customer to believe that she may have a disease.
b.) Also refers to the male
cock, whereas the
cock being the stick that is placed between the lips; thus a lip-stick. Derived from the possible coating of the lips with sperm during oral sex as the male
cock was brushed across the lips. This more than likely led to the development of the lip stick container; shaped much like the male
cock, which the female brushes across her lips to apply it.
c.) Sexual slang for oral sex, as in “sticking”(the cock being used as the stick)
fucking the lips; also know as “
face fucking”, and “
head banging”.
