selfie-cam
The camera that faces the user on an electronic device from the side with the main interface. It usually refers to cellular phones and tablets, but is not limited to this alone.
Vain, conceited, and/or narcissistic people will consistently verify their existence via a selfie-cam. This includes posting photos to social media, storing photos on their phone to seek approval from peers at a later date, and/or using it for the purpose as a mirror.
