Fangenius is just as it's root words defines.
"fan" for
fantastic and "genius" for genius.
It was created as a need to evolve from simply responding "genius" to things said that you like. Genius was simply not enough and the need to express how
fantastic something was
naturally spawned the evolution.
I coined this phrase back in 1997....
i have heard it uttered loosely from people's lips.
i think it's time to spread how fangenius of a word it actually is.
