When someone who, after reserving an OG-Mudbone amount of schpunk for an extended period of time, releases his "seed" with such ferosity that he lets out a roar of relief and the meanest, biggest load ever (basically cums a water bottle or 5). It ejaculates with speed and power, and no condom can hold it back. It is the Spermasourus Rex, the true ruler of the Animal Kingdom.
"Yo dude! How'd it go last night?"
"Man, it was a freaking Spermasaurus Rex! It was the mega load! It even tore the condom, and she just drowned in it!"

Imagine this scenario. It's cold outside, and you're wearing a half-sleeves shirt. To get your arms out of the cold, you pull your arms into your shirt, with only your hands poking out of the arm holes. That is called T-Rexing.
The weatherman said it would be 80 degrees, but it was so cold I had to resort to T-Rexing the entire time I was outside.

“See that Rex bro? He bought a 22B Brighton and did a full STI swap with a TD04 and coil overs, stage 2 clutch, Cobb access port, turbo timer, TGV delete, Perrin master cylinder stopper, and a short throw, then he took it to his buddy’s shop and had it tuned. It’s putting 440 at the wheels.”
