personality trait defined by one's ego being so large it has consumed one's testicles.
This particular type of self absorbtion begins in the individual's testicles where they are eventually consumed. The lack of testicles often leaves the individual with a large cavity beneath the penis where the testicles once hung.

Hoppy: Oh, he's been diagnosed as being egotesticaless.
Hoppy: Yeah, his ego ate them. So even though he is a pussy, his ego still makes him a giant prick. Quite a conundrum that one can be an equally huge dick as he is a pussy.
