Source: the tail of a large diffuse reverb played backwards. Two decorrelated pink-noise beds (left and right) stand for the dense reflections; a soft band of sustained partials stands for the pitched ring of the room.
Body: in a forward reverb the highs die first, so reversed they arrive last: the wash starts dark and muffled (low-pass near 350 Hz) and opens up to a bright, airy hiss while a band-pass "suck" sweeps upward. A thin detuned partial stack glides up a fifth-ish interval, giving the pull towards the cut.
Envelope: an exponential swell (a reversed 60 dB decay) that is slow at first and accelerates, reaching its peak at the very end; then a hard cut, softened only by a 3 ms fade so it stays click-free. A soft transient "air push" is deliberately absent: the sound ends exactly where the hit would begin.
Variation: length, brightness, tone (tonal ring amount), width, and rng-shifted partial detune.
