A nihilistic upper-class male who cares of nothing but material possesions, looking flawlessly handsome, and making absurd amounts of money. One bateman is rarely distiguishable from another due to the fact that they wear similar clothes and all sport the same chic haircut. Batemans are inherently violent, usually on a combination of booze, coke, and/or pills, and are above the law... so beware.
"Have you met nick's brother chad?"
"The one that works on Wall Street? yeah...that guy is a total fuckin bateman.
