Someone who is oblious to their surroundings, acting either like they are dead inside, a robot or just completely in another world. It could be a cause of the way they act, dress, speak or think.
"Bro, did you see John today?"
"Yeah bro, he's such a cadaver"
If you're name is Cadaver...You are hot. You are a bit of a control freak with literally everything. You get anxious a lot, but you still have confidence that inspires and radiates hotness. You are very loyal, and you are that silent mysterious type with trauma that is somehow sexually arousing to literally everyone. Last but not least.... You have big boobies. Whether you are a man, women, or something else. You have big boobs, there are no exceptions
"wow I never realized how big Cadaver's boobs are."
when my grandma died, they carried her casket in a cadaver car .
