One of my favorites is "Tyrannosaurus wrecks" — it never gets old. I also like saying someone's outfit is "rawr-some" when it's bold. If you're enjoying these, read more puns and jokes to dig into the prehistoric fun. Came up with this one recently: "Velociraptors are terrible at parties because they always try to raptor attention." And for the herbivore fans: "I'm just a triceratops in a world full of T-Rexes." Hope these help with your project!
