Midwest culture

Midwest culture refers to the social patterns, values, and sensibilities associated with the central United States—roughly the Great Lakes and Plains states.

It connotes friendliness, modesty, and unpretentious directness, sometimes called "Midwestern nice." The stereotype includes practical work ethic, casserole-based cooking, and a tendency to avoid confrontation or overt displays of wealth.

That's very Midwest of you might describe excessive politeness or self-deprecation.

The culture is often contrasted with coastal attitudes perceived as more ambitious or status-conscious.
