The Pornhub Community Intro meme stems from the distinct orange-on-black visual and drum-heavy audio signature of the adult website's community section. It gained massive popularity as a 'bait-and-switch' prank, where a seemingly innocent video suddenly cuts to the recognizable intro, causing immediate panic or laughter for the viewer. This meme relies heavily on the 'if you know, you know' factor, tapping into the collective recognition of the site's branding. It is widely used across social media to prank unsuspecting friends or to humorously highlight moments of incriminating behavior where total silence would have been preferred over a loud, public reveal.
