A loud and angry way to tell someone they are being a total waste of air and need to stop talking.
My mom said, 'A nice cup of shut the fuck up,' when my brother kept whining about his bad day at school.
In the middle of a Zoom call, my boss said, 'A nice cup of shut the fuck up!' after I accidentally turned on my microphone.
My friend texted me, 'A nice cup of shut the fuck up!' because my cousin kept telling bad jokes during the movie.
