Get the Extended Back mug.A not so rare disease/deformity some people (male or female) encounter in their life. This disease/deformity will bring down someone's self-esteem & hurt their chances at dating a 10. Extend-o-back aka Extend-o-neck is when that ass never makes an appearance. This forces your neck/upper back to extend all the way down to your ankles.
