Get the rexmug. 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, i was a freaking Spermasaurus Rex! It was the mega load! It even tore the condom, and she just drowned in it!"

Glenn: “Keith, what are you? A chanceasaurus Rex?”
