A Chundersaurus Rex is a person who, after thought of as being able to handle their alcohol, has one spectacularly inebriated night where their inner identity reveals itself and their stomach contents leaves their body with a roar of defiance.
Usually quite quiet until drunk, and the chundering tends to become a habit at inebriated social events involving Jack Daniels.

An older woman too dried out for the watering hole who rubs up on every man that walks into the bar. It is a natural predator. Anyone under the age of 30 should beware of its powerful prowess.
The Cougasaurus Rex is often seen grabbing the backsides of unsuspecting young men.
The Cougasaurus Rex is known for the 20 second hug with a neck kiss thrown in.

Characteristic qualities include: grey hair, glasses, and smelly old lady perfume.
Be Aware: At any given point a Cougasaurus Rex may sneak up behind you and sink her claws into an innocent young buck.
