Punch down fold
Or other folds that I have never heard of like labia fold, etc.
I seem to see people commenting on using the origami fold the most but that may just be me. :p Do you have to change your folds if you use a different cup, if you have ever done that? If the results are what I think (less people using the C fold), why do all the cup companies only refer to the C fold in pictures and sometimes, describe the punch down fold (I never understood the instructions for it)?
I understand they can't give us a whole book on folds but when I first got my diva cup, I hated the C fold and the C fold looks so big to me. Finding this group helped me find a fold that worked. Although, I was using a half version of an origami fold for my diva cup/mooncup and when I switched to lunette/lady cup, I had to figure out why I couldn't get it right anymore because the flexibility was different. I had to relook at the folds because I was leaving out the last few steps of the origami fold.
