A social attack meant to: oppress, despirit, embarrass, confuse, and destroy the target person's confidence; it's a mind-fuck. This attack is done usually by a teenage girl, or girl in her early 20's. This is a subclass of gaslighting and troll attacks.

The attack can be complex; it involves the girl talking to her target (the mark) using any mixture of bullshit, like:

1. Portraying/acting out a sarcastic character with an altered voice

2. While obnoxiously taking a contrarian position to something obviously opposite in the discussion. Basically, two-face shit

3. And using a series of gas-lighting techniques-- or blatant lying-- to weaken confidence (e.g. "Stopp. Read the room. No one thinks your funny"--when really the exact opposite is true)

4. Fake-complimenting the target (i.e. only to tell them they look like absolute shit, say, ten seconds later)

5. Feigning interest in the target's life only to lead them down a road of sudden and precise personal insults (i.e. ..so much for sharing your traumatic life events with someone)

Once the target buys into the attacker's positive advances (i.e. the trigger point)-- the attacker will switch their personality (and position). Then, attack the target by saying the opposite of all the positive shit they said before-- this can include lying, gaslighting; the goal is to do all the emotional damage. This process can vary, be complex, drawn-out (or short), and repeated over and over again to the attacker's fucked up satisfaction.

This is a form of activism that started with the millennial generation and became main stream due to Gen Z and the “fairy comment” subculture.

The influence of the movie Mean Girls and other cliche holidaywood coming of age films centered around teenage drama made “mean girl behavior” more acceptable for a period of time. As millennials grew up and became socially aware, these former mean girls abandoned their tactics of criticizing other women.

With these dormant mean girl skills, many millennial mean girls created mean girl activism. Mean girl activism took all the typical high school mean girl behavior and changed the target to elected officials or other sources of influence in order to rally support for a specific cause.

Girls who are bullies and use "girl agression" (nasty comments, trickery, deceit, excluding people from events, spreading rumors, stealing boyfriends,etc.) to manipulate others are now using these skills to help push for policy reform and legislative change . They will use text messaging, email, three-way-calling, social media blasting, and any other weapon at their disposal to acheieve these goals.

These girls are often popular because everyone is either afraid of them or wants to be like them. They tend to have armies of followers comprising their clique. Mean girl activists use this popularity to their advantage to influence their clique to sign petitions, make donations, attend protests, vote, and cyber bully elected officials.
“I used to be such a mean girl in high school until I grew up and matured into a mean girl activist. Now when I feel that urge come along, I call the major and list out every physical imperfection I can find on his face as well as what cosmetic procedures he needs to fix them. After that I demand he defunds the police”

“Mary’s social media feed is full of mean girl activism, but she did help raise thousands of dollars to support the fight against racial injustice”

Passive aggressive behavior designed to exclude another female from your friends, from the conversation, or just to make her feel uncomfortable and unwelcome in general.

think of all the fake smiles followed by the eye-roll, or blatantly ignoring another girl to make it known she's unwanted - both behaviors are girl mean.

when a girl asks for one of your rings it means she’s claiming you as hers. By having one of your rings she has proof of you being hers.
