A phrase exclaimed when surprising someone with a gift or something unexpected, or after performing a magic trick.
(as Jere is re entering the restraunt) "Yo Jere, where'd you just go"? "Did you see that hottie walk by a few minutes ago? Ta Daow! I was gettin her number!" (as i'm pullin out a piece of paper out my pocket)
A hip-hop version of the common exclamatory phrase "Ta-Da!", most often referring to a big booty, a extraordinary wad of cash, or any veritable prize that's worth gloating over in a wide-eyed and vocal fashion.
(man points toward new set of spinning rims on his 1984 Buick LeSabre...): Tadaow....TADAOW!
