Get the feinstein mug.
An obnoxiously loud, nasally, attention monger who speaks too frequently for their brain to produce intelligent information fast enough to make the utterances worthwhile; simply to remind themselves that they are intelligent enough to conversate in the first place. they are correct and knowledgeable on any topic, especially finance and politics, regardless of whether or not they are actually correct and knowledgeable. they also are in denial as to their own self worth and social status, which is usually low due to their overall cocky disposition, irritating voice, and amount of time spent obsessing over monetary gain and career goals which results in the neglect of a spirtual side and eventual social ostracization. this dilemma is made up for by taking an out of date, unrealistic, pretentious religion very seriously.
