We already have quite a few *_request tags which can be useful if you don't know/can't find the tag for said item.
There is already tagme, but that somewhat covers everything, and in some cases only one or two items that you cannot find the tag for.
Quick example would be post #1145071 , the items these two characters are holding. Both items aren't really searchable on danbooru or google.
It seems a bit stupid to affix the tagme tag to this since it's only a few items.
It isn't so bad for items copyrighted characters are holding since usually you can just find it by looking through the character tag.
Main suggestion is, would it be worth creating a thread for requesting tags of objects? (Somewhat similar to what we have for http://danbooru.donmai.us/forum/show/37461 )
This could hopefully get rid of a lot of images in tagme that have been tagged due to not knowing names of a few items.
