"I got the cliffnotes." noun. Used to brush people off during a potentially long-winded story or explanation of current events.
When someone is talking or telling you a story and you don't want to hear it, say "Thanks but I have the cliffnotes," to shut them up. This works in many ways, like if someone asks if you've seen a movie, etc., you can say you have the cliffnotes (to the movie). You can experiment and enjoy pissing people off.
