When a man, laying flat on his back, is having sex with a women who is sitting on top and facing forward. Right at the very moment when the man is about/during to cum, the woman surprises the man with a full force punch to the solar plexus, aka the middle of the chest. This with cause the mans face to contort and his arms to pull into his chest; like a retarded T-Rex.
