The line comes from Sweet Transvestite, the introduction song for Dr Frank-N-Furter in The Rocky Horror Picture Show, released in 1975 and based on the 1973 stage musical The Rocky Horror Show. Tim Curry performs the number as the flamboyant scientist welcomes Brad and Janet to his castle, and the song quickly became one of the film's most quoted moments. As Rocky Horror built a lasting midnight-screening and online fan culture, short clips of the introduction were shared as reaction audio for confident, theatrical moments, keeping the line familiar to audiences who may never have seen the full film.
