The best of all the dinosaurs. The Bunkasaurus Rex is a long legged, ginger colored creature who has a strange obsession with cats. It is attracted to all things jewish, and things with the initials N.M. The Bunkasaurus Rex is sometimes called Bunky as a nickname, and it enjoys raping people's formsprings. It likes to eat rats and Cape Cod potato chips as snacks, and loves the restaurant "Friendly's". Especially Fribbles, when they get in her hair.. It is a naturally homosexual animal, and it loves its sister Kate. Salad Fingers and MCalor bring joy to her life. Ok I could go on but I'm tired. pce.

The Bunkasaurus Rex likes Addy Lambert and Marjorie Stewart Baxter.

Cuckosaurus Rex 

A genus of the family Cuckold. Identified not simply by the recognition of archetypal cuck behavior in men, but also an accompanying tyrannical pride in his cucking. This behavior need not be objective cuckoldry, it needs only be the personality stereotypes found in men which are summarily taken advantage of by women.

I first identified Jimmy simply as a Beta male. After learning he had a girlfriend, I realized he was a Cuck. Then noticing the ways in which he is proud of how he lets his girlfriend get the better of him I concluded he was actually a Cuckosaurus Rex.
