BUR #34381 has been approved by @evazion.
mass update favgroup:38574 -> grabbing_own_flat_chest
mass update favgroup:38574 -id:8356734 -id:6859793 -id:2263915 -id:2263164 -id:2264401 -id:684784 -id:354452 -> -grabbing_own_breast
This BUR will create grabbing_own_flat_chest, which will then allow grabbing_own_breast to imply breasts. It uses a favgroup I created with the grabbing_own_breast flat_chest search.
The first line of the BUR will add grabbing_own_flat_chest, and the second line will remove grabbing_own_breast while excluding any posts that have both a flat chest grab and an actual breast grab.
