A good many of the worst knocked about were talking a bit wild, but I never heard the guy with the Chinook wa-wa again.
Several forks, into which the river is divided, unite to the west of wa-wa.
Merry laughter often broke at the clumsy efforts of white mans tongue to imitate Indian wa-wa (talk).
1926, in jazz slang, in reference to the effect on brass instruments made by manipulating the mute; of imitative origin. Later also in reference to an electric guitar effect. As an imitation of the sound of a baby crying, it is recorded from 1938. Wah-wah pedal is recorded from 1969. Cf. Chinook jargon wawa "talk, speak, call, ask, sermon, language;" Cree (Algonquian) wehwew "goose," Lenape (Algonquian) wava "snow goose," all probably of imitative origin.
To talk: to be seen waggin' your chin with a sleuth (1920+)
