Instagram's message from a trend takes one of the internet's favorite guilty-pleasure TV tropes — Pretty Little Liars' anonymous texter "-A" — and turns it into a quick, looping Reel. The setup is disarmingly simple: creators film themselves doing something quietly embarrassing, then overlay a shady little callout note signed "-A" that exposes the habit on screen. Because the on-screen text carries the joke, the format works for any niche and any account type, which is exactly why it's spreading.
Reference example: creator @mattie.newlin called out her own bad desk posture with the line "better fix that posture, shrimpie." One specific habit, one line of text, seven to fifteen seconds of video — that's the entire recipe. Below is a practical guide to recreating the trend, adapting it to your niche, and giving your version the best shot at looping.
What the Message From A Trend Actually Is
Every message from a trend video follows the same two beats. First, a casual clip of the creator doing something slightly shameful — slouching at a desk, skipping a skincare step, snacking on the couch at midnight. Second, a text overlay styled like a mysterious anonymous message that calls the behavior out by name and signs off "-A," the same signature the TV show's villains used. The comedy comes from the contrast: the footage is ordinary, but the note treats it like a scandalous secret.
The format runs on original audio or a simple voiceover rather than a licensed trending sound. That's a bigger deal than it sounds — it means business accounts, brand pages, and creators who avoid trending audio for licensing reasons can all post it without friction. And because the joke lives in the text overlay, the filming itself can be extremely simple: one static shot from a tripod is enough.
How to Film Your Version in Under 30 Minutes
Start by picking one habit you can show, not explain. The strongest entries all share one trait: the embarrassing behavior is visible in the frame. "I skip leg day" is weaker than a shot of you walking past the gym; "my desk posture is terrible" works because viewers can see the slouch the second the note appears. Write your "-A" line before you film so you know exactly what the camera needs to catch.
Keep the clip between seven and fifteen seconds. That's short enough to loop several times while someone reads the overlay, and loops are the engagement engine here — each replay counts as another view. Film in natural light, prop your phone up at a slight angle so the scene feels candid rather than staged, and act naturally: the joke lands harder when you look genuinely caught.
Writing the Perfect "-A" Callout Line
The note is the whole punchline, so give it the attention it deserves. Keep it to one sentence, written in the shady, knowing voice of an anonymous texter. The formula that works: specific behavior + playful nickname or jab + the "-A" signature. "Better fix that posture, shrimpie. -A" works because it's specific, it teases, and the signature completes the reference.
Avoid two traps. First, don't make the line so long it needs pausing to read — if viewers have to pause, the loop breaks. Second, keep the tone playful, not mean. The trend roasts the creator's own habits; turning it on someone else, even as a joke, changes the vibe and can land badly with your audience. Self-deprecating humor is the whole appeal.
Adapting the Trend to Your Niche
The reason this format travels is that almost every niche has a catalogue of relatable bad habits. Skincare creators can call out sleeping in makeup; fitness creators can expose their terrible squat form or the pre-workout ritual they swear by; work-from-home creators have endless material in unmade beds, daytime pajamas, and "quick" breaks that last an hour.
Creator-blooper versions are also doing well: posting the outtake reel — the mispronounced brand name, the ring light falling over, the third take of an intro — with an "-A" note narrating the failure. This doubles as authenticity content, which audiences consistently reward. Whatever your niche, pick the habit your followers already joke about in your comments; inside jokes get the strongest reaction.
Posting Tips to Maximize Loops and Saves
Time the text overlay so it appears one to two seconds after the clip starts. That delay creates a small beat of curiosity — viewers see the candid footage, then the note drops and reframes everything they just watched. On the replay, they read the note immediately, which is what pulls them into a second and third loop.
Post the Reel during your audience's peak evening scroll, since this is light entertainment content rather than morning-utility content. Add a simple caption that invites comments without begging for engagement — something like asking followers what "-A" would say about them. And if the trend fits your brand, post a second version in a different niche context the same week; formats this simple are cheap to make, and the second attempt often outperforms the first.
