Hats off to them for not doing anything to their social media profiles that involved profile pictures of dicks.

Buzzfeed Video had pairs of friends swap phones for a day and the results were, uh, pretty much what you'd expect. Participants messed around on dating apps, posted weird Facebook statuses, and checked in at weird locations. Things definitely could've gotten a lot weirder. If my friends have my phone for more than 5 minutes, they will have already changed the language to Greek and signed me up for multiple porn services. Come to think of it, maybe I just have shitty friends.
