A word used to describe an individual who causes a large reverberation in the form of jostling people around when they flop down onto a couch/sofa etc.
Ellie was being a total bumbardier when she jumped onto the sofa next to me, I nearly flew across the room!
1) e.g. "Yousa thinkin' dis isa Bombad game?! Oie boie..."
Translates to: "You think this is a superb game?! Oh boy..."
2) Jon: "What is going on here? What's a 'Bombad'?! I don't know who was in charge of this, but they are clearly an unrecognised genius. You had, like, AAAALL the Star Wars lexicon and you chose THIS?! You went with Bombad."
