Place this reaction right after the long build in your edit, then follow it with the Sad Violin Sound Button to underline the drag, or lead into it with the Sudden Suspense Sound Button when a wait takes a bad turn.
About this sound
A short spoken Russian line lasting about five seconds, a voice asking 'and how long will this last' in a flat, fed-up tone. It gives listeners that drained, impatient feeling of being stuck in something that will not end soon, perfect for dragging moments.
