As usual, the Shi*thouse lawyers come out of the woodwork. I can't tell you if there's "a list" of words the feds will come after you for, but I can say from my (insane) experience on the S&P show that the line isn't all that vague if you know what you're doing. Examples? Why sure.... (please don't edit - the following examples are real. I know, I was there)
You can not say "stick this in your ass". You can say "stick this up your ass. The latter statement does not imply insertion into a body orifice.
You can not say "I like your p*ssy" (unless, of course, you justify it with a comment about a cat). You can say "I think you're a p*ssy". The latter is a slang that describes a perceived character trait, not human genitalia.
You can not say "I think your as*hole stinks". You can say " I think you stink, as*hole". Again, the latter describes a perception of the person, not a body part.
I could go on (and on, and on, and on) with examples directly from the (pre-cc) show, but you get the point.
Argue all you want that the people/show/station could get in trouble for statements like those above, but you won't win. Language like this was part of the show on a daily basis and nobody ever went to fcc prison over it.
