grammar - Possessive + gerund + object pronoun

I'm reading The Great Gatsby and there's one part when Tom Buchanan is arguing by phone with George Wilson about a car, and Tom says the next:

Very well, then, I won't sell you the car at all ... I'm under no

obligations to you at all ... and as for your bothering me about it at
lunch time, I won't stand that at all!

the part:

[...] and as for your bothering me [...]

has a structure like:

possessive adjective + gerund + object pronoun

I had never seen such a construction, so my question is:
Is there something elided in the sentence, and what's the meaning of the sentence?

Thank you in advance.

Answer

In school I was taught that gerunds take a possessive pronoun and that's that. But it kind of makes sense if you consider that by definition a gerund is a present participle masquerading as a noun. If we substitute an actual noun, we might get something like, "your disturbance [of] me at lunchtime." The subjective "you" would never fit in this construct, and thinking of "bothering" as a noun should help make this rule clear.
