mustanger 

In military slang, an officer who previously served as an enlisted soldier.

Best officers I encountered during my time in the service, bar none, were "mustangers" (former enlisted who became officers) and warrant officers. Most of the others (ROTC, OCS or West Pointers) were frag-fodder.

Roy Mustang 

A character from the anime/manga series Fullmetal Alchemist.

Roy Mustang is the very picture of an attractive, sophisticated man in the prime of life. With his dark, piercing eyes and clean-shaven, baby-faced visage, the infamous colonel attracts a great deal of attention from admirers. Roy's dark hair - perhaps in keeping with his persona - is worn casually unkempt, falling over his eyes; in more formal or somber situations, however, he is known to wear it neatly slicked back. He is also DEAD SEXY... IN A MINI SKIRT!!!!

On the surface, Roy seems to be a shallow and self-absorbed man, infamous among many of his colleagues and subordinates alike for the selfish and narcissistic aura he gives off.
At the core, he is a remarkably devoted commander whose primary focus and personal duty is to his friends and subordinates. Though he hides it well behind a veil of cynicism and self-importance, Roy Mustang is a man who cares deeply about the people who trust and support him

"Have you seen roy mustang?''
"Yeah he's dead sexy, in a mini skirt!!!!"

Mustang Cobra

The best all around performing mustang built by Fords SVT department. It was produced in limited numbers depending on the year. The most popular and sought after are the '93, '93 cobra R, 2000 Cobra R, 2003/2004 Cobra's aka terminator. There is also the GT500's but in my opinion they fall into another category.

That mustang cobra is bad ass. It just smoked that piece of shit honda.
