to escape ones lips in a moment of sheer exuberance - a bursting energy from inside needing to be verbalised instantaneously. Known to have cured cancer, Woo-woo is sometimes complemented with a small jump followed by a fist of victory raised high into the sky's.
Woo-woo is a way of life.
*please note: Woo-woo can be shortened – if one is unable to contend with verbalising previously mentioned bursting energies – to:
"Tonight's gonna be ruddy brilliant. Woo-woo!"
"Here, Cole, what do you make of this? Woo-woo!!"
"Err, eeh, argh -- A-woo!"
