A finsta is a combination of the words Fake & Insta(gram). When people have a finsta they post pictures they only want their closest friends seeing instead of their regular instagram(rinsta)followers to see. Usually a girl has a finsta and boys arent supposed
to follow it. Finstas arent supposed to be taken seriously and it doesnt matter how many posts or followers you have. Finstas are mainly kept private and have funny of clever usernames.
Oh my gosh that's hilarious post it on your finsta!
I need a new username for my finsta.
Uh oh... I just posted on my rinsta instead of my finsta!!
