"In the end, it took a team of 35 people to develop a filter to make {the IBM Watson supercomputer to} stop swearing and wipe the Urban Dictionary from his memory to prepare him for his future as 'a diagnostic tool for hospitals.' We can only hope that they missed some profane nugget hiding in a dark recess of his hard drives, which doctors will hilariously discover when Watson starts referring to a colonoscopy procedure as an 'asshole spelunking'."

asshole Sharpe

Expected assholishness over standard deviation of assholishness. Higher asshole Sharpe indicates a better, more consistent, more reliable, asshole.

Did you talk to Patrick? He's never not an asshole. His asshole Sharpe is off the charts.

Asshole Nod 

That moment, when you see your boss at the office, or some old friend on the street, and the person looks you directly in the eye and nods without saying a word because they are too much of a coward to speak or apologize for being a utter douchebag at some time in the past.

Dude: "Hey bro did the bossman come talk with you?"
Me: "No dude, he just sort of gave me the Asshole Nod."

Dude: "Wtf is wrong with that guy, he's such a douche and a pussy?"
Me: "Word"
