"__ is a sloothiersaurus-rex with a short-arm-long-neck complex."
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!"
A gay man who runs around with a straw forcibly felching unsuspecting civilians, and then disappearing into the night leaving no trace of his actions but the humiliation of his victims.
Did you hear about my buddy Jack, he got attacked by the Feltchasaurus-Rex and will never be the same, but between me and you I think he might have liked it.
