A Washington D.C. noun (Again an ass-backwards/boneheaded misuse, not unlike the way DC morons call a woman's cunt, a cock) for a pretty, sexy, young, (say, less than 26 years old) girl or woman, usually brown-skinned to jet-black, who dresses to tease exposing/outlining her: legs, rump, chest. Oh yeah. She definitely needs to be fat-free, but not skinny. The more athletic, the better. A plus feature is carrying herself with the kind of confidence found in a woman who knows she can make you cream your pants on a hard-grinding slow dance, as practiced in DC.
Said w/ gusto:
That bitch there is a stallion!
