It is usually the secondary Instagram account that someone has.

This account is typically private and only shared with close friends.

This secondary account is usually very personal and emotional, sort of like a diary, or silly, filled with memes and humorous photos. It is meant to be hidden from one's family members or the general public.

A private or secret Instagram where you can post things only your close friends or family can see. Lots of famous people have finsta so people don’t see things in their private life. Regular people can have finsta too. They usually have weird names and random messy posts. If someone follows your finsta and sees a really ugly picture of you they might show everyone and laugh at you. Better be careful who’s follow request you accept.
“Can I follow your finsta?”
“No”
“Why?”
“It’s private”
“Im going to hack you and show everyone a ugly picture of you if you don’t let me see”
“Ok fine geez the user is @rlly.ugly_jimmy_84828”

About to or preparing to do something. This term can most accurately be classified as a contraction containing the words "fixing" and "to". Some may prefer to characterize it as a compound word as it does not contain an apostrophe.
