fries limp with the weight of their own grease

[meliss]

Hi. Could you please explain me what does "limp" mean here? Maybe "lacking firm texture, substance, or structure"? But how could it be "with the weight of their own grease"? Thank you.

Yes, that's right.

But how could it be "with the weight of their own grease"?

Why not? The excess grease made the fries limp (soggy, bendy, not firm).

It adds to the idea that they aren't crispy, but soggy and fatty.
