When people talk about how sharp their lenses are, they'll often include what a picture, and and then a segment of that picture. They'll refer to it as a "100% crop".

Now, I know what cropping of a picture is, but I don't understand the 100% part. What's it referring to?

It just means that after You have cropped You do not resize it.

The way I think of it is the pixels you're looking at are 1:1 with the ones that came from the camera.

Think of clipping a coupon out of the newspaper.

I thought 100% crop means 100% enlargement of the image and then crop it. Similar to zooming in the font 100% in the pdf document in Adobe Reader, no?

Yes as long as Your definition of "enlargement" does not mean actually upsizing.

But it really does not matter if You view the photo at 50% or %100 when You crop. The important thing is not to do any resize of the image.
