I don't use Snapchat myself, but I have been roped into a few pics on Snapchat thanks to the filters. Usually their filters just add things like dog ears or dinosaurs to your pic, and they're fun enough for a distraction, but it's all quite harmless.
That is, until Snapchat released its latest filters, one of which adds traditionally female facial features, and one that adds traditionally male facial features. You probably don't even need me to tell you where this is headed — straight for weirdsville.
