When a woman has just completed her period and wants a little extra time before jumping back in the sack again.
After a week of abstaining from sex while my girlfriend had her period, I was flabbergasted when she told me that she was still on an extended vaginacation.
Vaginatastic (n.): The less popular version of bonerific.
origin(s): Considering the current delicate social conditions, advocates of the word "bonerific" coined the more female empowering version of the word "vaginatastic" as a token of political correctness and unity.
