Every now and then, I come across things in person and or online and I really have to ask myself, WTF is it and sometimes, I have to ask how in F do you use it? And, I know I can't be the only one and so, I thought I would start this thread for everyone to share the things you all see and wonder the same things.
With that said, WTF is this thing? AND, how the F do you use it??
