Literally the best thing that ever happened to Snapchat ā nay, HUMANITY ā was the introduction of the filter where you can swap faces with any photo on your phone's photo roll.

I mean come ON how good is this?
Snapchat is lit with the face swap
Look at this pic of me faceswapped with Jonathan Cheban! Tell me this isn't the thing nightmares are made of! It's a horror machine and I love it!

Then, on May 13, 2016, a day that will live in infamy, something terrible happened. The camera roll faceswap filter temporarily was removed from Snapchat.
PEOPLE WERE NOT HAPPY.
Snapchat taking away the camera roll face swap is like when Egon took the puppy away from the little girl in Ghostbusters II
