I think this is the big link:
Quilter's Dictionary & Acronyms ... a consolidation of previous posts
I was really active in the on-line quilting community around Y2K but then I got married and spent a lot more time in real life and gaming and things, and when I found this site there were a lot of terms I didn't know so I had to ask as well.
Some of that is because of the spread of new techniques and different naming terms, so 20 years ago we didn't talk too much about edge to edge (which I would now call e2e).
Flimsy is commonly used here to mean what I would call a "completed top that isn't a quilt yet". Flimsy is definitely shorter.
