Place it right at the point of the wince in a reaction edit, then follow with Emotional Damage for an over-the-top complaint or Bruh for a second reaction. It also works before a laugh track in a short skit about bad sleep.
About this sound
This is a sub-second voice clip of someone saying 'neck hurt' in a clear, flat American accent, with both words enunciated close to the microphone and no music or background noise. The deadpan, almost formal delivery makes it funny, turning a small ache into a dry punchline for stiff necks, bad sleep positions and tiny injuries played for laughs instead of sympathy.
