Shutting Up Now

"Optimus Prime: "Bumblebee, my small little friend. You look...different." Bumblebee: "Yeah, I just totally got rebuilt. I feel better than ever. I feel like a gold bug." Optimus Prime: "Ha Ha! And that's who you'll be from now on, Bumblebee: Goldbug! Goldbug: (uneasy laughter) Uh...thanks...Uh, gee, Optimus, I was kinda thinking I could still be called Bumblebee." Optimus Prime: "Quiet, Goldbug." Goldbug: "Shutting up now, Optimus.""

- The Rude Awakening Of Optimus Prime

This is where a character 'voluntarily' decides to be quiet, removing themselves from the argument/conversation. This can be through defeat (being proven wrong), threat, everyone staring at them accusingly or suggestion.

Common phrases would be "I'll be quiet now" or "Okay, I'll just shut up" or simply silence. One key theme of this trope would be that they really do want to talk but humiliation or perhaps painful humility stops them.

Another form of this is when someone realises they're babbling, are clearly making a losing argument and/or are getting increasingly off topic, ending their spiel with "I'll just shut up now".

See also Digging Yourself Deeper for the reasons people may end up shutting up and Chewbacca Defense for a discussion of why this is an admission of defeat. Compare And That Would Be Wrong, Change the Uncomfortable Subject, I Have Nothing to Say to That.

Contrast Preemptive "Shut Up".

Kyon: I am going to forgo speaking privileges for the rest of the day."
