When someone acts extremely lame. Where someone is really lame and it's sillier than a regular dinosaur on their silliest behaviour, resembling a "T-Rex".

Get the vagasaurus rexmug. Head coach of the New York Jets. Also a notorious big mouth who tends only to talk the talk and almost never walks the walk. While he has turned the team around, he still acts like he is the greatest coach who ever lived (when in reality people might give that title to Vince Lombardi, Mike Ditka, or Tom Landry). One can only hope he'll get his act together next season if it comes around (all signs point to probably not).
Guy #1: Man that guy is such a Rex Ryan!
Guy #2: I know, he's always running his damn mouth when he shouldn't.
