Virago

A shrewish woman. A second, archaic meaning is a masculine woman. Gama meant whichever interpretation would most infuriate the men. See also The Grand Duke.

Pronunciation: 
The correct pronunciation is open to debate. Most dictionaries say vih-RAY-go, but most people seem to prefer vih-RAH-go. I suggest using whichever form is more popular in your environment.
