BUR #5466 has been approved by @evazion.
create implication cum_in_cup -> cum_in_container
create implication cum_in_bowl -> cum_in_container
create alias cum_in_glass -> cum_in_cup
I think it would facilitate searches for images that have containers of various types, including cups and bowl, by making cum in container the catchall tag for the other two tags. There is already a lot of overlap between the cum in container tag and the other two tags and cum in container sounds more generic than the other. Also, the definition of cum in cup already includes images of drinking glasses filled with cum and there are more images tagged with cum in cup than cum in glass, so the latter should be made an alias of the former.
