sisterwife

Close female friend (or Dave) who believes that she holds a position of importance in the life of the Queen, even though she really just sleeps on various surfaces in Party Central. A sisterwife doesn't pay rent, but is domiciled in the home of the Queen Sisterwife and has no problem leaving mass amounts of garbage and refuse for the Queen to clean up. Sisterwives often take pleasure in naked spooning with the Queen Sisterwife and her random conquests, and also have no shame in belittling young Sicilian bedfellows. Whilst a sisterwife has no respect for the Queen's minions, she will often find solace in handholding with the aforementioned young men who find themselves in the lair of the Queen.
