perspicacity

That word that Drew Barrymore taught me in the first ever episode of Chelsea on Netflix.
1. Basically, having acute mental vision or discernment
2. Shrewd
3. The unusual power to see through and comprehend what is puzzling or hidden
4. A Jew, or someone who jews you out of something
5. A backhanded compliment

"You dick...you used your perspicacity to jew me out of my money!"
"I admire your perspicacity and spirit."
"You perspicacious asshole!"
