Get the jason bourne'd mug.
To disappear to someone's knowledge from the face of the earth without notice. When you wake up with a girl and erase all of your information from her phone to the fullest, block every form of social media, and then speed off. To block someone from every form of contact (unless they attempt so by extreme measure) from your life. To totally vanish and dispatch someone or a group of people from your life. Really useful when that Tinder chick turns out to be a psycho.
1. Dude, I hooked up with the hottest girl last night, but in the morning she was a total bitch. I Jason Bourne'd her ass. She doesn't even remember my name.

Spouse: "Did you forget the milk, again?"
You: "Whoops. My bad, love of my life, but I Jason Bourne'd as I walked past the dairy aisle."

Destroying the Evidence:

Spouse: "Did you get rid of the body like I told you to?"
You: "Damn. I'll admit, ball and chain, that I'm a highly-trained assassin that works for a shadowy government organization that I can recall almost nothing about... i.e. I Jason Bourne'd the corpse."
