A person who is so smart that it's stupid. This phrase defines a level of intelligence that shouldn't be possible or a level of intelligence and wisdom that is very rare. This phrase does not just
define a person who thinks outside of
the box, but it defines someone who goes a level beyond that which breaks the conventional thought pattern of
human wisdom.
A lot of
people misuse this word and
think that it means a person who is stupid that tries to act smart, but that's not what this phrase means. The reason 'stupid' goes before 'smart' is because it enhances the word smart. There are levels of smart like: very smart, insanely smart, and finally stupid smart. Since stupid is the polar opposite of smart it means that the phrase "stupid smart" is the highest level of smart that exists as a phrase.
