The "Selfie" has become part of our culture. On vacation? Take a selfie at the beach to rub it in everyone's faces. Out with friends? Take a selfie to show how much fun you had (or help you remember what happened). Voting? Depending on where you live, you may want to hold off on that selfie, or it could get you in trouble.
This week's pop music trend or epidemic, of sorts? Wisdom teeth removal. Ariana Grande got one of hers yanked earlier this week and now Lady Gaga is recovering from the same procedure, which isn't major. It's more of an annoyance than anything.
