A big lizard-like thing that lived LONG LONG AGO! Back with the cavemen...i think. umz they were super rad. and ate eachother, or we're vegetarians! And said alot of "GRRRZ" and "RAWRS" and "jhefuwegfjegfwuefiwbi". And some had wings and they had....scales and they were so cute. But then they decided to move to like another galaxy and now they are no longer..... Veggie dogs anyone?

An extinct reptile that roamed the earth, but those weird kids who think theyre cool like to pretend that theyre dinosaurs. Dinosaurs are cool, so they pretend to be a dinosaur because the think it'll make them cool.

TOM:Steve you puked while we were at the bar last night you idiot.
STEVE: Oh yea?
TOM: Yea, but you you were also doin the best dinosaur i have ever seen.

Get the dinosaur mug.
A neeky person who is overly-fascinated by the sciences and spends more time with their calculator than on facebook. Rather than being embarrassed by their enthusiasm, a "dinosaur" is proud and they often distinguish themselves to others of their species by performing a "dinosaur dance" with their hands shaped as claws, often in public places.

Notable dinsoaurs would include Ross Geller of Friends and distinguished engineer Catriona McGill.
"ahhhh mate your such a dinosaur"
"Gosh, catriona is such a dinosaur shes whipping out the claws, trying to attract some scientists!!"
