Couch Commando know it all

Person who plays militaristic fps all day while giving quotes on ranges of guns and whats possible in real life in military situations when he has not been in any military service. Couch commandos are usually very obese.

When I was playing online and complained about someone shooting me across the map the "couch commando know it all" than said it was possible and gave me the ballistics maximum range under a controlled environment and than said see its possible.

a know-it-all

an offensive term for an arrogant person who professes to know everything in 1 and only one subject but in reality they know absolutely nothing in that subject.

please do not confuse a know-it-all with a pundit, or someone that is blowing fairy dust up your skirt. they are 3 completely different things.

emo know it all

Anyone with enough sense to completely avoid the emo trend. Those who recognize the fact that emo is a false-genre cobbled together from bits of other music subcultures and that its adherenents are fixated on clonish fashion statements and overmoted, contrived negative emotions.

Q: Why aren't you emo?
A: As an emo know it all, I understand that emo is dumb, and therefore choose to ignore the trend.
