Someone who is unbelievably
slutty, to the extent that they can be considered whoretacular = Whore + Spectacular.
Also can be used to describe someone that, while a whore and incredibly
promiscuous, is still amazingly so and generaly admired for the entertaiment she provides.
J-Dog: "Man that girl, M, is such soooo
slutty. But
wow, what a great body!"
Daniel: "Yeah man, she sleeps with everyone! M is a whoretacular!"
