create implication bike_shorts_under_skirt -> bike_shorts
Any image depicting bike shorts under a skirt must also be depicting bike shorts in general.
118 pages of images have both tags: https://danbooru.donmai.us/posts?tags=bike_shorts_under_skirt+bike_shorts+&z=5
6 pages of images violate this implication by not having the bike_shorts tag: https://danbooru.donmai.us/posts?tags=bike_shorts_under_skirt+-bike_shorts+&z=5. I looked at a sample of those images and all the ones I looked at did indeed deserve the bike_shorts tag.
