Implicating butt_cleavage → butt
Link to implication

Reason:

Ass_cleavage was created due to butt_cleavage being aliased to butt, (forum #221886, forum #221887).
For the sake of consistency of other tags, butt_cleavage should be unaliased and instead implicated to butt, and ass_cleavage should be aliased to butt_cleavage.

EDIT: The tag implication butt_cleavage -> butt (forum #221988) has been rejected by @NotMeNotYou.

Like I said in the other thread, the cleavage tags are problematic. Would be better to name it something like plumber's_crack instead.

So ass_cleavage and butt_cleavage should be aliased to plumber's_crack, which is then implicated to butt?

Bumping to prevent automatic rejection.

I still think it's very odd that cleavage implies clothed and breasts, but butt_cleavage doesn't imply anything.

+1 for plumber's_crack

This one has plenty of synonyms. :p
