Sierra-Hotel 

A term used by fighter pilots (and those who want to be) which means "Shit-Hot!!" Whatever is described by that term is wonderful. The words 'Sierra' and 'Hotel' are part of the aviation phonetic alphabet.

Extremely beautiful, smart, and elegant. Sierra is the type of person to never give up. She'll hold her head up high even in her darkest hours and will help you even if she's hurting. She usually has a natural sparkle that never dies.
