1. Pushing people into swimming pools. Now that we all have electronics in our pockets, the prank becomes an expensive disaster.
2. Facebook.
3. Shirts and posters that use the “Keep Calm” phrase, like “Keep Calm and Eat Nachos” or “Keep Calm and Do the Harlem Shake” or whatever.
4. MTV.
5. Using text language, like the letter “u” instead of the word “you.” No one texts like that anymore.
6. Wearing those silicone wristbands for different causes.
7. Wearing a backpack with just one strap. Using both straps is okay again.
8. Smoking cigarettes.
