The shout comes from drag queens Trixie Mattel and Katya Zamolodchikova, RuPaul's Drag Race alumni and hosts of the comedy web series UNHhhh, where hi gay became their signature greeting to fans. Clips of the duo yelling it in unison circulated on YouTube, Tumblr and later TikTok as a queer in-joke and Pride staple. Its sub-second length made it ideal for soundboards, so it spread as a downloadable meme sound for intros, coming-out jokes and drag edits, where it remains a recognizable callout.
