Bottled water. 'Wa' came originally from some half-remembered scene in a movie about Helen Keller, where she stuck her hand under a running faucet and uttered her first word: WwwaaAAaaaaAAAAhh! 'Bawa' was coined to differentiate between bottled water and plain ole water--which is, of course, 'tapwa'. Example: Thirsty? We've got ice tea, tang, or bawa.
