This page is an attempt to list YASIs that come up on several NetHack-related IRC channels. I have made this list separate from my other list.

Attribution will be listed wherever possible, and feel free to add any more that aren't here. While YASIs are not intended to be taken seriously, they might still find some use if listed here.
