Boondabah

Ha, Bad noob! May be said while initiating combat, may also be said just for fun! Scream it loud! BOON-DA-BAH! It's fun to say! Can be used to define something that was incredibly easy.

Cessy screamed "BOONDABAH!" as she slipped her rapier between the night elves legs and then cut him in half.

Cessy then declared "Boondabah" afterwards to signify that it was cake.
