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.

boolaahhh 

The spelled out version of the noise you make while puking, vomiting, throwing up, or blowing chunks. This usually comes about due to having the flu, drinking to much alcohol, or being out of shape. Or when someone mentions something you find completely disgusting.

Jennifer asks, "Austin try some of this haggis, it's really good!"

He replies with only the noise "Boolaahhh"
