Term invented in the early 2000 by Dr Mario. Term used to describe an individual that talk sh1t on the internet completly protected in their home home.
They would never do that in public, being shy, timid, reserved individual. But because they have complete impunity, they show their real morality and talk, act like sh1t.
Kid(BBQ) : you are a stupid ass h0le, I did your mother last night...
Dr Mario : Oh come on don't be a keyboard toughie now...
