The Butterfly Effect

An illegal underground sex move where a man approaches a female in a group of friends, generally at a bar. After failing to hook up, the man walks away, then waits for her to be separated from her party. Once alone, he proceeds to knock her out and have his way. Once finished, he quietly returns her to the bar, so she wakes up seamlessly to her friends, as though nothing happened.

That hot chick totally blew me off, so I gave her the butterfly effect.

The Trump Effect

The Trump Effect. (Condition, feeling, sensation, or phenomenon) Is the result of President Trump's continuously embarrassing comments and abhorrently childish behavior that makes people give up hope, realize the bar of decency and integrity has been set to rock bottom, and/or creates a general feeling of apathy, despair, and resignation after constantly being subjected to persistently obnoxious behavior.

Mary: "Hey, Scott, I noticed you no longer harp about the stupid things Trump does or says."
Scott: "I suffer from The Trump Effect. Whereas I used to care, I realize his behavior is never going to change and that we will just have to suffer this embarrassment until he is no longer President."
