create alias crotch -> crotch_focus
Mere weeks ago, I pondered in the Discord "Hey, we've got ass focus, breast focus, and (unfortunately) foot focus tag... how in the heck don't we have "pussy focus" or "penis focus" tags, considering how many images focused on those?" I considered it far too gargantuan a task to even consider, so I didn't even bother with it. Until Deep Danbooru informed me of a tag that exists!
Lo and behold, apparently we do have a tag fitting that description! The crotch tag wiki says:
The area between the legs where they join the torso.
Used for images where the point of view is blatantly focused on the crotch region, specially around the perineal area (i.e the vagina)
Which 100% fits the bill! I'm thinking that in order to better align with the others, putting that "_focus" bit at the end will make it more obvious as to what the tag is for. Theoretically someone could go a step further and specify between "pussy focus" and "penis focus" ( @Admiral_Pectoral ), but that's up to your discretion.
