Someone that clearly didn't do their research and jumps straight into historical debate. A person that parrots off "facts" they learned in their high school history class and pretends to know the thoughts, intentions and motives of historical figures. Someone who pretends to know history. These people typically think they are above everyone else intellectually just because they know a minute fact that has no application to the current conversation, as if it changes the whole picture.
Random person: "Why did Hitler lose to Stalin again?"
Armchair Historian: "Bro, like Hitler knew nothing about history. Napoleon invaded Russia and lost due to Russian winter. That means that Hitler was retarded because he invaded Russia and lost due to Russian winter."
Actual Historian: "Well that's simply not true, Germany was heavily outnumbered by the allies in WW2 and suffered constant attacks by British air on their infrastructure, making a total victory on the Eastern front nearly impossible. Not to mention Hitler didn't invade farther north than the Baltics. The Russians had even less supplies for their soldiers than the Germans did despite bombings on their infrastructure; the USSR didn't issue enough blankets or clothes for their soldiers on the front line to survive their own winter."
Armchair Historian: "B-b-but NAPOLEON! NO! NO. THAT CAN'T BE TRUE! RUSSIAN WINTER! COME ON! BELIEVE ME!!!!"

A person who spends their free time wirting pointless letters and posting worthless comments in local newspapers, A person who watches daytime TV quiz shows such as Eggheads, The Chase and Pointless. He will always say how much more interteligent, he is, than the contestants on said shows. A person who thinks they know everything about anything, when really they don't. A person who reads the Socialist Worker newspaper and buys the Big Issue, to show his grassroots views when actually, he lives in a council house.
Joe thinks he could do better on Eggheads and claims to know everything. The man is full of shit Armchair intellectuals

A person who declares everyone else at fault for any problem, while they themselves claim it's not their responsibility to help solve the problem. They absolve themselves from anything remotely challenging that might tarnish their appearance of blamelessness, especially with technology issues. They love assigning blame while remaining safely removed. They also like to point out how other people inconvenience them.
The armchair perfectionist blamed his wife and kids for the wifi problems, saying "I didn't have anything to do with this. This is all on you!"

Someone who comments on news or current events of the day from the comfort of their own living room.
Andrew didn't know jack about the war in Iraq, but as an Armchair Anchor he felt it was his duty to comment on things.

Someone without any background in phycology who thinks they know everything about it. They usually diagnose people or themselves with little to no knowledge of how these illnesses work.

A person, particularly in science academia, who *never* actually does any work, but loves to obnoxiously pontificate during meetings on a wide variety of topics, usually exposing the fact that they have no practical knowledge on any topic whatsoever. When it comes time to publish, they insist that they be included on the author list because they contributed "expertise" and "guidance". They butt into private work conversations, and immediately use the royal "we" to describe what "we" are doing on the project.
Such individuals are invariably total ass kissers to those in charge, which explains how they are often able to progress in academia despite knowing fuck all, and contributing nothing.

"The new graduate student is a total frickin' armchair genius. He's coming down the hall... quick, close the door and pretend we're not here before he tries to pretend he's in charge of the lab project we've been working on for the past five years."
