What do you define as a scrap that you put into your scrap bin?

I just watched a Bonnie Hunter video where she says that she cuts her scraps into strips sized like she knows she will use in the future - 2.5, 2, 1.5, etc.

My scraps are odd shaped pieces that I think are big enough to be sewn into something like a crazy quilt. If I have enough fabric left over big enough to cut strips, it is put on my foam board for future use. I may not want to cut it into strips in the future. Maybe I want bigger squares from it.

Do you cut good size leftovers into strips? What do you define as a scrap?

As a side, I did see a video where a lady took her like-colored scraps and sewed them together into a "fabric" that she could then cut up for a quilt block. Her quilt was beautiful.
