Place it in the middle of a slow scene, after Bruh answers the first dull idea, and save Emotional Damage for the moment the waiting finally turns into a complaint, so the sequence builds instead of repeating itself.
Über diesen Sound
This is a short 2.5-second voice clip stretching the word for boredom into a long, flat 'tediooo', with the vowel held until the complaint itself sounds tired. It feels weary and unimpressed, like a sigh made into a word, and it lands best when nothing is happening and saying so is the whole point.
