For example, an easy one, Ninja, Bow, FB, shuriken, NSB, etc.
It can be any word, really, but I imagine some would be easier than others. Nouns for example, lol.
If youd like you can make your own class for the word you used or leave it up to other people in the topic.
I think this should be pretty fun and can't wait for some of the more interesting names and the oddball reasons for the items on them
Ill start with a few.
