For some reason breast slap is being used simultaneously for posts where characters use their breasts to slap something/someone and posts where someone is getting slapped on the breasts. I separated all the posts into 2 favgroups, one for slapping with breasts and another for slapping breasts, similar to the existing slapping with penis and slapping penis tags.
