Gay rapper Cazwell's new single is called "No Selfie Control." I think we all know someone who just can't get enough of their own image. I have an acquaintance who changes his Facebook profile photo at least every other day; I liked him better before I knew he was that vain.
Fun fact: I've never taken a selfie that I was happy with and was willing to share. I stopped trying and instead ask someone else to take the photo. You'd be surprised at what can happen when you stop a random stranger in public and ask them for a favor.
(Please note: This doesn't apply for sexy selfies. Don't go asking strangers to take pictures of your junk. If you do, you shouldn't be surprised at the reaction.)
