snapchat

If your parents are unfamiliar with Snapchat filters and perhaps a little "thick", it can be quite easy to mess with them.

So, when a child shows up with a square head during a WhatsApp conversation, motherly instincts are sure to kick into gear.

As is the case with Rebecca Owen, a receptionist from Manchester, UK, and her mother, who was certain her daughter's square head was the result of a food allergy (salmon paste) or even drugs.
