A person, usually female, who is fat but doesn't know it, or refuses to believe it. An obeserexic person will most likely where tight clothes, not knowing that all their blubber hangs out.
Did you see that chick Jasmine? She's huge, and she was wearing a shirt that was at least five sizes too small! She's so obeserexic.
