Finstagram, finsta for short, is a mixture of Fake & Instagram. People, usually girls, get a second Instagram account along with their real instagrams, rinstagrams, to post any pictures or videos they desire. The photos or videos posted are usually funny or embarrassing. Only your closest friends follow this account.
