A figurehead is an insecure mama's boy who likes to act tough on internet chat rooms and forums. Often spends hours researching material to come across as knowledgeable, but more times than not will be incorrect. A figurehead is easily spotted when confronted with bogus information. A figurehead will become combative, resorting to name calling and throwing fits.
When called out on his obvious lack of knowledge on the subject, figurehead started ranting, raving, and calling everyone an idiot. He had nothing else to backup his comments.
