The usual masculine disillusionment in discovering that a woman has a brain.

The line is a sharply ironic comment on gender expectations: men are portrayed as assuming women’s intellectual inferiority, then feeling “disillusioned” when confronted with evidence of a woman’s intelligence. The phrasing flips the usual romantic script—where disillusionment follows the discovery of flaws—by treating a woman’s mind as the “unexpected” trait. Read as social satire, it exposes how misogyny can be embedded in supposedly ordinary reactions, and how women’s competence is framed as a violation of masculine comfort. The quote’s bite lies in its economy: “usual” suggests this is not an exception but a recurring cultural pattern.
