breast_rest is just a specific case of breast_squish, and no one uses the former tag anyway. I had some difficulty making this suggestion because breast_rest is already aliased? A big thank you to anyone who can help.

Never mind, I figured it out. breast_rest is for posts like this and breast_squish is for posts like this. Resting breasts are just uncommon.

for future reference, you should use this and this for suggesting aliases and implications
