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.
