This sound is a generic censor beep rather than a quote tied to one specific character or scene. The bleep became familiar through broadcast TV and radio standards, then spread into online editing where creators use it to imply profanity, adult jokes, or embarrassing slip-ups. It remains popular because a single short tone instantly communicates censorship and often makes the hidden line feel even funnier. In meme edits, it is often paired with an awkward moment reaction or another abrupt comedic cutoff for extra timing.
