Excerpt from this article (an “oldie but goodie”):
Here are a few of the ways that girls are leveraging Instagram to do much more than just share photos:
To Know What Friends Really Think Of Them
In the spot where adults tag a photo’s location, girls will barter “likes” in exchange for other things peers desperately want: a “TBH” (or “to be honest”). Translation? If you like a girl’s photo, she’ll leave you a TBH comment. For example: “TBH, ILYSM,” meaning, “To be honest I love you so much.” Or, the more ambivalent: “TBH, We don’t hang out that much.
To Measure How Much a Friend Likes You
In this case, a girl may trade a “like” — meaning, a friend will like her photo — in exchange for another tidbit of honesty: a 1-10 rating, of how much she likes you, your best physical feature, and a numerical scale that answers the question of “are we friends?” and many others. Girls hope for a “BMS,” or break my scale, the ultimate show of affection.

A Way to Retaliate
Angry at someone? Don’t tag the girl who is obviously in a picture, crop her out of it entirely, refuse to follow back the one who just tried to follow you, or simply post a photo a girl is not in. These are cryptic messages adults miss but which girls hear loud and clear. A girl may post an image of a party a friend wasn’t invited to, an intimate sleepover or night out at a concert. She never even has to mention the absent girl’s name. She knows the other girl saw it. That’s the beauty of Instagram: it’s the homework you know girls always do.
