When viewed from the side, if you can see the crease under the breast where it returns to the torso while the nipple is still concealed, you are seeing Sideboob.
Whereas Absolute Cleavage is all about showing as much of the area between the breasts as possible, this trope is about exposing the outer sides, roughly from the armpit to the nipple. There is a variant where the nipple is intentionally concealed by the arm, the hand, or the legs, and occurs frequently in topless fashion photography.
