I'm off to the gym for a shower, rather than using my own hot water, FW!!
Sorry it's cold in here, haven't had the heating on in years, FW!!
Usually used by a female as a way of saying that she accepts the fact that she is abusing her hottness and taking advantage of multiple interested parties simultaneously and leading them on. This advantage taking can be emotionally, physically or monetarily. Similar to a player, but not necessarily a slut.
