Riley
1.  Traditially a man's name, not a female name - the reason being the actual meaning of the world and old world values, which are indeed ebbing in this day and age of homopolitan sweater wearing coffee house schmoozes.  The word means "Valiant" in old Irish.  As in valiance, the virtue which was the very paragon of Knighthood, see differences between words, Knight and Lady to gain a rudimentary understanding of gender within the English language and prior Celtic influences in a historical sense.    

2.  An individual who is on the verge of lashing out physically or near entering into a fight, sometimes seething with anger.  One might also see the word modified as 'riled'.  

3.  Any individual with a fiery disposition, regardless of egocentric issues or your petty drama, one who is willing to make a stand in the face of adversity.  

4.  A sexual term indicating great excitement and fervor, high energy and dedication toward another's satisfaction.
