@Blesh, I believe the disallowed uses is when it's obviously being used to insult someone.
Saying your dog has been going crazy over the neighbour's pancake is fine (since it's perfectly reasonable to assume that you are not referring to the neighbour's wife/daughter, but rather their female dog).
However, accidentally revealing that the neighbours don't really own dogs and it becomes obvious that your intent was an insult
Even if you are really tight with them and you use pancake as a show of affection.
I do have something interesting to ask the mods though, it's fine with the commonly known words, but what about saying something like:
I don't give dem Billy Hunts a Donald Duck. Those Aristotles.
haha, well aside from the obvious. like is it ok to say "that peerless run was bitchin'!"
or "that quest chain is a pancake!"
i also wonder if the phrase "wicked pissah" would be allowed. i miss that phrase.
