A slang term for an obeese woman's breats. They tend to be deformed, covered in stretchmarks, and bulging out of a shirt that is too tight. People with lardsacks tend to think they are very attractive and try too pull off a get-up that is not even appropriate for those of supermodel status.

Origin: A nasty girl who OVER exposes her breasts to attract attention to them and divert everybody's eyes from her poor excuse for a body.
