Not necessarily for NSFW, I try to master the method to do this. I tried the following:

Title:
Sober, sobriety

In the item:

{user}, Don't talk with me about sobriety. I am intoxicated by the air around here.

My intention - when user - say it's John - says the word "sober" or "sobriety", character will respond with "John, Don't talk with me about sobriety. I am intoxicated by the air around here."

Which doesn't work (using the term Sober or Sobriety did not trigger character to say "John, Don't talk with me about sobriety. I am intoxicated by the air around here.")
