She said Monkey D. because it reminded her of Monkey D. Garp so I think she had a fight or something with garp before. And as far as we know big mom is all about sweets and kidd only sunk two of her ships which had nothing to do with her sweets(And it looks like she doesn't care about her crewmates. proof: she ate one). But luffy ate all her sweets and directly declared war to her, plus he's the son of garp.
