Sideboob is the registered trademark of a fashion line by the company Some Brand in Germany (www.sideboob.de). The name Sideboob originates from their renowned shirts with deep and wide side cutouts, which allow a view of the female and male breast seen from the side.
I love these SIDEBOOB Shirts, because they allow a nice view of her breast from the side. Show some side-boob!

When a female has large enough breast that when she has her shirt off and she is viewed directly from behind, you are able to see the sides of her breast.
While looking at the back of a female, her boobs are visible on the side. Thus, side-boobs are present.

The act of breastfeeding a baby while both mother and baby lie horizontally, facing each other, so that the baby easily falls asleep. A preferred breastfeeding position for night feeds.
After awaking to the sounds of her infant screaming lying next to her, the mother turned around and gave him side-boob and he quickly went back to sleep.

n. What is seen when a topless woman (or very fat man) turn far enough to the side to see the breast, but not the nipple. Many movies, in order to keep a PG-13 rating, show only side boob. Braless women who wear sleeveless t-shirts are notorious for side boob.

The side view of a female breast that is usually unintentionally exposed by a female wearing a loose shirt or revealing bathing suit. Arguably almost better than actually seeing a fully exposed breast, the sideboob is the "profile" of a breast without exposure of the nipple. The side boob gives you a great sense of what you are working with while also keeping it PG-13.
