Why the fuck does Aunt May call them Wheat Cakes? ALL pan-cakes have wheat in them, did she not get the memo? Is this some weird Earth 616 lingo?
Using an odd choice of language in a movie places the character in a particular time/place or helps cement their characterization. Aunt May is supposed to be "homey" which, to a lot of the US, could be old southern hospitality. "Wheatcakes" hearkens back to not only to that characterization, but simultaneously reminds some viewers of the depression and the deprivation of the time that required less than ideal substitutions in common foods.
To Aunt May, being able to serve wheatcakes is a blessing, and she is honoring those she is serving, while the script is also cementing the idea that Aunt May represents home, and all that goes with that feeling of comfort, safety, and peace.
Or the script writers are a bunch of looneys.
But then I'm not entirely sure what you're talking about, other than it's probably a reference to some spiderman something or other, so I could be way off base. Perhaps she's an alien, and is having trouble with american words.
