Cuirass
This one is fun. First of all, because any word that includes ass is fun, especially when it ends in -ass. But also because it's part of a suit of armor, and let's face it, armor is one of the key elements when it comes to bad-assery.

2. (Life Sciences & Allied Applications / Zoology) a hard outer protective covering of some animals, consisting of shell, plate, or scales
