Ah, that's an interesting question! The phrase "Margaret packs a box lunch" is used as a euphemism for lesbianism. In this context, it’s a playful, coded way of saying that Margaret is attracted to women.

Why "Packs a Box Lunch" Means This:

This phrase is based on wordplay and innuendo:

"Box" is sometimes used as slang for female anatomy in English.

"Packing a lunch" or "packing a box lunch" suggests being interested in or prepared for something.

So, "packing a box lunch" uses indirect language to imply that Margaret is interested in women, without directly stating it.

This kind of euphemistic language is often used in movies or shows to convey potentially sensitive topics with humor or subtlety.
