'Now You're a Man' was written by Trey Parker for the 1997 comedy film Orgazmo and performed by DVDA, his comedy rock band with Matt Stone. The over-the-top macho anthem became a cult favorite among South Park fans and early internet comedy circles. Clips of the chorus circulated on YouTube, forums, and later TikTok as a shorthand for mock masculinity. Its short, punchy structure makes it ideal for soundboards, and it endures because the joke lands instantly without needing context.
