new tags suggestion - nsfw

so i wanted to suggest a tag idea. i have no clue if they already exist, but they’re for vore images.
 
basically gender + prey or pred
 
like the femsub / femdom etc tags
 
so, like:  
fempred / femprey  
malepred / maleprey  
futapred / futaprey
 
i hope that makes sense and i’m doing this right i’m not very good at wording ^^;
