Awkward Dinosaur 

A hand gesture made by placing four fingers on a surface with the middle finger straight out to resemble a dinosaur similar to a brontosauraus. Used in an awkward situation to release the tension. Very similar to the Awkward Turtle. This was created by John Crawford of Crystal River and used in his classroom.

When telling a joke that no one gets, one can sometimes get a laugh by using the awkward dinosaur in conjunction with a "Roooaaaaar"

Mr. Crawford discussing the Constitution "And thats why they call it clause and effect!"

crickets begin to chirp

"Rooooaaaaar" with awkward dino creates laughter
