A term that means to undress, and then re-dress oneself.

Often as a means to change one's clothes but sometimes just a means to get naked and then get dressed again.

Josh went to skin and back again but now has on a Speedo!
Josh went to skin and back in the woods just to feel the breeze between his knees.

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!
