Wide angle distortion is when the subject of whatever you are taking a picture of is to close to the camera and it will look large and almost wide as well and it will get distorted features. You might want to avoid this when you are doing a proper selfie or any portrait for that matter, but when you want to sue it, it would be useful for up close objects maybe, but not for people I would say.
