Everyone's done it. I'm doing it right now with the word "cool" in my head and on the phone. Saying a word over and over until it lacks meaning in every context you use it. Suddenly "I'm going to the store." gets the same response from me as "Some girl just fell off the runway on America's next top model!"
Protip: I really like going to the store, but I really REALLY like it when a girl with freckles basically rolls across the top of the water in a giant hamster ball. At that moment, I knew I wanted a giant hamster ball and a pool, so that one day I could be that awesome. And I said "cool." What is wrong with me?
The same thing that's wrong with everyone who speaks english. Each of us is creating our own individual vision of newspeak. I try to mentally count each word I use one day each month. I get distracted halfway through the first meeting of the day and end up with things like "synergize", "leverage" and "skillset." Then I die a little on the inside.
