fatstagram 

When a person crosses the threshold of weight gain in which their past photos on their instagram are no longer recognizable as their current self. This causes them to delete all of their photos and replace them with current (fat) photos in a very short period of time.

Did you see all of Jessie’s posts this week? She’s definitely making her fatstagram.

Fapstagram 

When a person uses their Instagram solely or mostly to stalk (sometimes follow) members of the opposite sex and fap to them.

Tom has got quite the fapstagram. He doesn't ever upload any pictures, but take a look at his search history; they're all women.

Finstagram 

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.

Hey that picture you posted on your finstagram was so funny.

That picture is so funny you should finsta that.

Finsta that shit nowwwww!

Oh let's take a picture for my finstagram.

facetagram 

A social media merger. A hybrid of Facebook and Instagram. A world where features and posts are identical. It would be so boring. It’s already partly true

Please stop facetagramming your posts. Don’t send the exact same posts to Facebook and Instagram.
