A recent trend in the "beauty product review" sector of YouTube is the "100 Layers of [x]" trend. It started out with someone doing 100 layers of nail polish, but then branched completely out. Some recent "100 Layers of Foundation" video got over 6 million views. Since then, people have done beauty products like mascara, eye shadow, spray tan, and even full layers of makeup.
Getting closer to WAM interests, there is one video so far for 100 Layers of Face Paint, and a few for 100 Layers of Clay Masks in the last day or two.
This seems like a trend just begging for WAM interpretations. 100 Layers of Marshmallow Fluff, anyone?
