I've heard conflicting reports:
Dae-oo (without the "W")
Dae-oh (no "W", just flat "O" sound)
Dae-Woo (Like "Whoo-Hoo, and it rhymes with nearly everything)
Most people refer to it as the last one, myself included, but some people who really know the name swear its Dae-oo.
I feel like such a cretin for posting this, I hope I don't lose any respect.
