Ancient people at your work place that are usually bitter and old that need to retire.

dinosaurs are a myth. don't tell me your stoopid facts, DINASAURS ARE FAKE AND YOU KNOW IT!

The term dinosaur refers to a band or belt that one would use to make their veins more visible when injecting something.(herion)

Dinosaur, or for short, Dino, was originally the great animals that roamed our earth from the Triassic period to the Cretaceous millions of years ago.

Now, the mighty creatures have been reduced to nothing but a idiotic scene fad.

The best animal known to man kind they are not extinct like many think they are just in the witness protection program much love for these fantastic animals=

the word "Dinosaur" is slang for Heroin...

(not the syringe and not the "a band or belt that one would use to make their veins more visible")

Calling heroin the "dinosaur" came from an earlier slang used for Heroin "Tar". It's a common belief that dinosaurs became fosil fuel or "tar-like" over millions of years... The La Brea tar pits (in Los Angeles, CA) is an example.

The other slang contributing to the use of the "Dinosaur" meaning heroin is the saying "monkey on your back" referring to any addiction controlling you.

In the song Pool Shark by sublime Brad sings "tying on the Dinosaur tonight. ...use to be so cool."

Here he is referring to how his recreational heroin habit had grown into a full blown uncontrollable addiction. Describing his "monkey" as a "dinosaur" he had on his back can be interpreted many ways.
Brad was acknowledging the enormity of his problem, his increasing consumption, his inability to control it and also acknowledging the fact that all heroin addicts face extinction every time they get high... extinct ...like a dinosaur.
Tragically poetic!

The "tying on" or "tying off" is slang for the process of finding a vein to shoot up or more so ...the complete ritual of shooting up any drug to get high... but I digress.

The newest thing for all the scene kids to like.
