What is Green Line Test?

A photo-editing format where users draw vertical green lines down two people in a picture to argue that whoever leans toward the other is the submissive or 'needy' partner.

Where did Green Line Test come from?

Twitter user @alpharivelino originated the format on May 2, 2020 with an edit of strongman Hafþór Júlíus Björnsson and his wife Kelsey Henson, captioned 'Don't lean in, strong man!'.

What does Green Line Test mean?

@alpharivelino tied the test to his 'sexual polarity' theory, arguing that a leaning man signals a 'weak and needy mindset'. Body language expert Joe Navarro called the theory 'rubbish' with no scientific basis.

How do you use Green Line Test?

Overlay a straight vertical green line on each person in a two-person photo, then compare which line tilts toward the other; the leaner is read as submissive, while the upright partner is read as dominant.

Is Green Line Test still popular?

Usage spiked twice: on Twitter in May 2020 and again on TikTok in April 2022 after viral videos by JackMacBarstool spread the format to couples content.

On May 2, 2020, Twitter user @alpharivelino drew green vertical lines over a photo of strongman Hafþór Júlíus Björnsson and his wife Kelsey Henson to argue his slight lean toward her exposed a weak, needy mindset. Critics mocked the thread within days, parody edits spread across Twitter, and the format roared back in April 2022 when TikToker JackMacBarstool applied the test to a picture of Kim Kardashian and Pete Davidson.

Overview

Users apply the Green Line Test / Don't Lean In format by overlaying straight vertical green lines on two people in a photo and reading who tilts toward whom as a sign of relationship 'polarity'1. Earnest posts cast the vertical partner as dominant and the leaning partner as needy, repurposing @alpharivelino's 'sexual polarity' theory even when the caption plays the whole idea as a joke3.

Parody versions ignore couples entirely. Posters have applied the lines to the collapsing Twin Towers5 and to classic Loss panels6, mocking the test's pseudo-scientific logic. On TikTok, a second life for the format produced earnest couple diagnostics and ironic takes side by side, with creators analyzing their own vacation photos next to viral celebrity edits1.

On May 2, 2020, Twitter user @alpharivelino posted two side-by-side photos of Icelandic strongman Hafþór Júlíus Björnsson, best known as The Mountain in Game of Thrones, with his wife Kelsey Henson. The second image had green lines drawn down each body to show Björnsson leaning toward Henson, captioned 'Don't lean in, strong man!'2. The original post reached over 130 retweets and 950 likes7.

Over follow-up tweets, @alpharivelino argued the posture signaled a 'weak and needy mindset' rooted in what he called 'sexual polarity,' writing that the feminine wants to 'lean into the masculine' and submit to his guidance3.

How It Spread

Mockery arrived within days. Justin Whang quote-tweeted the thread with 'Very disappointed to find out that the strongest man in the world is in fact a beta male,' reaching over 560 retweets and 9,800 likes4. User @sewcialism joked, 'Fellas, is it gay to embrace a woman?'8. Twitter user @MattMcGurn ran the green lines over the collapsing Twin Towers5, while @roun_sa_ville applied the format to a Loss edit6.

In April 2022, the format resurfaced on TikTok. JackMacBarstool posted two videos on April 11 applying the test to a photo of Kim Kardashian and Pete Davidson; the videos reached roughly 1.3 million and 9 million views within about a month7. TikTok users then analyzed their own relationships, with @aeroplanekelly and @claudiaashao posting boyfriend check-ins that reached six-figure like counts7.

Dexerto covered the TikTok revival, quoting body language expert Joe Navarro who called the test 'rubbish' with 'no science to support it,' alongside expert Janine Driver, who claimed that every couple she tested proved it accurate1.

How to Use This Meme

Creators typically place a straight vertical green line down the center of each person in a two-person photo, then compare how far either line tilts from true vertical. The person whose line stays upright is read as 'dominant,' while the leaner is read as submissive or needy1. Comedic versions apply the format to inanimate objects, such as the collapsing Twin Towers5 or Loss panels6.
