nobody's fool

Not easily tricked

Nobody's fool describes someone who is shrewd and not easily deceived or taken advantage of.

The phrase usually follows a form of "be": She's nobody's fool—don't try to lowball her.

It emphasizes practical intelligence and self-protection rather than formal education.
