Rivelino the Artist, a Twitter personality known for his dating and social dynamics advice, became an internet sensation through his 'Green Line Test' body language theories. The meme involves drawing vertical green lines through figures who stand straight (signifying dominance) and diagonal red lines through those who lean (signifying submissiveness). While originally presented as a serious method for analyzing relationship power dynamics, the internet quickly turned it into a parody. Now, users apply these lines to photos of celebrities, fictional characters, and historical figures to mock the pseudo-scientific nature of 'alpha' discourse or to ironically highlight humorous instances of bad posture.
