In playing a recent eroge (I always feel like Konata when on this forum/other sites) a description of breasts that I hadn't heard or seen used before popped up: Bomb Breasts. While the breasts were questionable in their accuracy in their shapes <-> description, one truth was undeniable was they were enormous beyong reason.
Putting my personal feelings/dislike of excessively large breasts, you think it proper/easier to group the very large breasts into the (what would be new) bomb_breasts tag - ones such as gigantic_breats, huge_breasts, massive_breasts, and other ones where the breast size goes well beyond even the largest breast size?
The other area where I see we could combine tags is with image resolutions. There's nearly an equal number of tags describing overly large images which (in most cases) don't really help much. Since the filesize is clearly posted on every image, adding the absurdres or insanely_absurd tag doesn't really help much; where in fact the actual scanning resoltion could be very low, just taken from an image that is (physically) very large (like a movie poster or banner) but its resolution is only 72 or lower, but still has a filesize or 4 or 5 mb.
Using something simplier like low_res (pretty self explanatory), high_res (though it would be based on the image resolution and not its size - a 250 x 250 file that's 4 mb is going to be at least 600+ dpi, truly a high resolution) then a large_filesize and enormous_filesize to notate images that are disproportionally large in mb's relative to their dimensions.
Sorry, I don't mean to ruffle any feathers here; imo there are a few tag groupings that have too many tags to describe the same characteristic. Sites like Moe.Imouto that have fewer tags but are more precise I find them easier to do narrow searches that don't require 4 or 5 +/- signs in their search criteria.
