@gdkar I read this as an impact happening on like some kind of building or structure and instead of properly crumbling, the object bounces off an beautifully, accurately(?!) modeled and impeccably flexed pectoral muscle the building suddenly develops, followed by the building flexing its biceps and yelling in Terry Crews' voice "POWERRRRRR" and doing rhythmic muscle flexes in time to music.
