"Analogous to tears, smegma is the compilation of secretions by ectopic sebaceous glands located in the prepuce, the seminal secretions of the Cowper's gland and the prostate, the mucin content of the secretions of the urethral glands, and the sloughed epithelial cells. It provides the necessary mucosal lubricant and moisturizer and is rich in sexual pheromones. The prepuce normally prevents detection of this phenomenally charged scent until the glans is exposed at the time erection takes place." - Robert S. Van Howe, MD

"Smegma is probably the most misunderstood, most unjustifiably maligned substance in nature. Smegma is clean, not dirty, and is beneficial and necessary. It moisturizes the glans and keeps it smooth, soft, and supple. Its antibacterial and antiviral properties keep the penis clean and healthy. All mammals produce smegma." - Thomas J. Ritter, MD
"Is smegma useful? Yes, certainly. It lubricates the cavity between the foreskin of the penis and the glans, thus allows smooth movement between them during intercourse ... Nature has ... provided a natural ointment, smegma, to ensure easy lubrication and protect this delicate region of the male genital organ. / To secure its even distribution, smegma is formed from the whole inner surface of the foreskin cavity ... Smegma production ... is concentrated in the cells of innumerable small prominences, minute microscopic protrusions of various shapes and sizes found on the inner surface of the foreskin cavity ... Sexual intercourse becomes a regular feature of life (in adulthood) and the function of smegma assumes its full value ... Freshly formed smegma ... is a wholesome lubricant--making for ease in erection and smoothness in sexual intercourse." - Joyce Wright, MD

Smegmas is when you throw a frozen block of dick cheese at the back of someones head in an attempt to knock them unconscious. As they are falling unconscious you yell Merry Smegmas. And start singing a parody of a Christmas Song.
Last Smegmas I gave you my cheese. The very next day you filed a lawsuit it was just a prank bro.
