Of the nature of Obama, pugnacious, belligerent, truculent when things don’t go his way, arrogant, egotistical, supercilious and extremely scornful of others in the most unpleasant manners, and ignorant, complacent and clueless in regards to finance and in running an organization.
When a person or a coworker (maybe even your boss) is trying to tell you what to do and how to do it in the most arrogant manner where he/she has no clue about the subject of the matter, yet he/she acts as if they have the best knowledge about the subject; or simply when someone is being arrogant and obnoxious, that person is being obamatic.
