"Teenagers create a fake Instagram account called a Finsta, usually with a smaller group of friends and family members. They experiment with alternate identities -- for example, acting like a jock and posting about their accomplishments before anyone else knows. Or they post about a new passion for screamo rock, but they are not ready to let everyone else know.
