When a girls tits point in crazy angles away from each other. The easiest way to tell if a girl has these without seeing her naked is to check her cleavage. If the start of where her boobs come out looks like it could hold a trapezoid shaped building block then she's fucked. Not literally.
Oblivious Guy: Oh my god man check out her she's so hot!!
Smart Guy: Yeah shes hot but check her boobs man she has Split Tits. It totally ruins her hotness.
