Unlike the infamous phrase "roo roo", roo Roo ROO is an endearing gesture of support for another human. Similar to exclamations like "go get 'em champ!" and "Atta-boy", roo Roo ROO is used to let another person know that you like what they are doing and what they have to offer. A person hearing roo Roo ROO will be invigorated with pride and fire. roo Roo ROO is commonly exclaimed in an athletic forum or during a physical challenge.
With a tear in his eye and a fist in the air a young man shouted, "roo Roo ROO" as his favorite sports writer destroyed his naysayers with the power of a well-constructed and well-supported argument.
