But who can pronounce it? We're better off trying to solve the Rubik's Cube.

Ok, when i saw this i thought the poster just made it up.
But i looked it up, and copyed this from "cooldictionary.com". Honorificabilitudinitatibus is a word used by Costard in act five, scene one of William Shakespeare's Love's Labour's Lost. It is (in the quotation) the ablative plural of the medieval Latin word honorificabilitudinitas, which can be translated as "the state of being able to achieve honours." Appearing only once in Shakespeare's works, it is a hapax legomenon.
And no; it dos'nt mean, "In Honor" But for uncommonness
i'll rate it 5

YAY!!! I can't even say the stupid word!
