Whose speech is more standard?

Penelope Eckert 2003

The linguistic forms we consider "feminine" actually indicate something else, like refinement, and that only indirectly indicates femininity.

But at Belten High in Detroit, bad grammar is associated with rebelliousness. Burnouts sue it a lot more than jocks. Jock girls use use almost no negative concord; burnout girls use it almost exclusively. It signals their rebellious attitude toward authority and school.

Nonstandard grammar is associated with toughness, and lower class girls must be tough. In "the halls of the academe or government," women cannot convey a folksy demeanor because they are more easily discredited as professionals than men. They cannot chance it.
