When a female has worked out too much or has gotten so fat that her back is very wide. Her head looks small compared to her vast back. The shape of the back resembles a king cobra with it's hood extended.
Lark, did you see Mona at the bar
Yeah, she has quite the cobra back, she should lay of the lat machine at the gym.
