Snot can be used to reduce friction. I know what some of you are thinking and you are right. The vagina does produce a slick snot! For those of you who were not thinking about that… whoops. Many organisms ooze snot over the outside of their body to help them move easier. Earthworms are a notable example that you may have experienced. Slugs, snails and other mollusks also use snot to reduce friction and glide. When you see a slug trail, you are really seeing a snot trail.
