When a man enjoys both giving and receiving anal penetration because his arms are too short to grasp his own dick. In order to achieve the ultimate euphoric state of a Sexual Tyrannosaurus , uncontrollable vomiting will occur due to the penetration. After the penetration the man (at times men) circle said man and ejaculate into his chest so he can grab the seaman with his small arms and lather the man juice into his barren chest.
Ryan's chest resembled a glazed donut as a result of the Sexual Tyrannosaurus he experienced the night before.

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.
