The exact origin of this recording is not documented, but its spread follows modern gym meme culture online. Tren is shorthand for trenbolone, an anabolic steroid long associated in bodybuilding forums and social posts with extreme size, aggression and side effects.

It remains popular because the joke needs no setup: one sentence signals obsession, bad decision-making and classic gym-bro humour in about a second.
