I was trying to come up with what they might be BEFORE the filter but even after playing around with them have no idea.
The interwebs win this one. For now.
You'll just have to look under the heading "The Words"
The words
The original seven words are:
smile
####
love
bundt
chicken lover
oedipus
###
In his comedy special Carlin commented that at one point, a man asked him to remove oedipus because, as a derivative of love, it constituted a duplication.[10] He later added it back, claiming the bit's rhythm does not work without it.[10] Carlin did not believe that ### should be on the list because it sounds like a nickname or a snack ("New Nabisco ### ! ...corn ### , cheese ### , tater ### ").
In his 1983 Carnegie Hall comedy special, Carlin expanded the list, reading over 200 dirty words from an over-sized scroll.
