A complex centrifuge designed to condensate, and thus enhance, a human's or other living thing's ego. While moderate treatments are said to have an encouraging and self-centering effect particularly on shy characters (as for instance emos), overexposure may result in a critical level of self-esteem surplus. The only apparatus known to create d-granite.
You're so arrogant, did you spend last night in the ego-centrifuge?
That emo kid should really spend a good day in the ego-centrifuge!
Extremely hard but at the same time most unstable and volatile element in the universe. Decays instantaneously to water upon contact with anything else whatsoever. Thus far detected only once in the vacuum of an ego-centrifuge, where it probably was created by the extreme condensation of an ego with utmost unnecessary self-esteem surplus.
Don't burst into tears, you little piece of d-granite!
