Extended Back

When a chick has no booty.

Guy 1: "Damn bruh, that female has NOOOO ASS."
Guy 2: "Honestly bro, she has an extended back."

extended back

A person (usually a female) who has no ass, but instead just a back that seems to extended to just about their thighs.

Look at that girl, she has no ass.. just an extended back!

Extend-o-back

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.

Oh My God Becky look at her extend-o-back. She must have forgotten her J-Lo booty underware!
