Green Line Test on Kim Kardashian and Pete Davidson: The 104M-View Video That Started Everything

The TikTok video that made the Green Line Test go viral: JackMacBarstool's analysis of Kim Kardashian and Pete Davidson. Did it predict their breakup?

Published April 2, 2026 · Updated April 16, 2026

The Video That Changed Everything

In April 2022, a content creator named Jack McGuire (@jackmacbarstool) posted a TikTok that would become one of the most-viewed relationship analysis videos of all time. He applied the Green Line Test to photos of Kim Kardashian and Pete Davidson — and the internet lost its mind.

The video accumulated over 104 million views, launched the Green Line Test from a niche Twitter concept to a global phenomenon, and sparked a debate that's still going strong today.

What the Video Showed

McGuire analyzed multiple photos of Kim and Pete taken during their relationship (November 2021 - August 2022):

Photo after photo, the pattern was consistent:
  • Pete Davidson leaned toward Kim in nearly every image
  • Kim Kardashian maintained a straighter, more upright posture
  • The green lines told a clear visual story: Pete = WEAK, Kim = STRONG
  • The video was simple — photos with green lines overlaid, set to dramatic music, with McGuire's commentary. But the simplicity was its power. Anyone could see the lean. Anyone could understand the labels. And everyone had an opinion.

    The Timeline That Made Believers

    Here's what made this video legendary:

  • November 2021: Kim and Pete begin dating
  • April 2022: JackMacBarstool's Green Line Test video goes viral (104M views)
  • August 2022: Kim and Pete break up after approximately 9 months
  • The internet erupted. "THE GREEN LINE TEST PREDICTED IT." Millions of people who had seen the video months earlier felt vindicated. The test had called it.

    Or had it?

    Did the Green Line Test Actually Predict the Breakup?

    This is where we need to separate entertainment from analysis.

    The "Yes" Argument

  • Pete consistently leaned toward Kim in public photos
  • Kim maintained distance and upright posture
  • They broke up relatively quickly
  • The visual narrative felt right in retrospect
  • The "No" Argument

    Correlation is not causation. Here's what the Green Line Test missed: The real reasons they broke up (according to reporting):
  • Busy, conflicting schedules — Kim's reality TV/business empire vs. Pete's comedy career
  • The 13-year age gap created different life priorities
  • Long-distance difficulties
  • Pete's career commitments in Australia
  • The relationship simply ran its course
  • None of these factors are visible in a spine angle.

    The confirmation bias problem: Millions of photos exist of Kim and Pete. McGuire selected photos that showed a clear lean dynamic. Different photo selections could have told a different story. The survivorship bias: Nobody remembers the Green Line Tests that were "wrong." The Beckhams have been "failing" the Green Line Test for decades — they've been married since 1999. Nobody makes viral videos about the test's misses.

    The Couples Who "Failed" But Stayed Together

    If the Green Line Test were predictive, these couples should have broken up:

  • David & Victoria Beckham — David consistently leans toward Victoria. Married since 1999, 25+ years.
  • Barack & Michelle Obama — often show slight lean dynamics. Married since 1992.
  • Blake Lively & Ryan Reynolds — varying lean in different photos. Together since 2011.
  • These counterexamples don't go viral because they're not dramatic. A test "predicting" a stable marriage isn't interesting content.

    The Cultural Impact

    Regardless of its predictive accuracy, the Kim/Pete Green Line Test video had an enormous cultural impact:

    On TikTok

  • The #GreenLineTest hashtag exploded to 500+ million views
  • Thousands of creators began making their own Green Line Test videos
  • Every new celebrity couple photo was immediately analyzed
  • "Duet" and "stitch" videos debating the results drove additional engagement
  • On Mainstream Media

  • Newsweek, Bustle, HuffPost, Glam, and dozens of other outlets published articles
  • Body language experts were consulted for the first time about this niche internet theory
  • The Green Line Test entered mainstream vocabulary
  • On Relationship Culture

  • People began Green Line Testing their own relationship photos
  • Some reported genuine anxiety about their results
  • A counter-movement emerged, with experts and creators debunking the test
  • The broader conversation about social media's influence on relationship perception intensified

    What Jack McGuire Has Said

    McGuire has continued making Green Line Test content but has also acknowledged its entertainment value. He applies the test to new celebrity couples as they emerge, maintaining the format that made the original video viral: simple, visual, dramatic.

    His approach — applying a consistent framework to a new subject — is exactly why the format keeps working. Every new celebrity couple is a new episode.

    The Lesson

    The Kim/Pete Green Line Test video teaches us three things:

  • Simple visual frameworks go viral — the Green Line Test reduced complex body language to a single, instantly understandable image
  • Timing is everything — analyzing the most-discussed couple of 2022 at the peak of public interest was perfect timing
  • Confirmation bias is powerful — when the couple later broke up, it retroactively validated a test that had no predictive mechanism
  • The Green Line Test is entertainment, not prophecy. Kim and Pete broke up for real-world reasons that no green line could detect. But the video that "called it" will live forever in TikTok history.
