From Board 8 Wiki

1 drink everytime someone says the word "Darkness" or "Heart"

1 drink every time Sora says "Riku" or Kairi"

1 drink every time Goofy and Donald die in combat

2 drinks every time someone says the words "Darkness" and "Heart" in the same sentence

feel free to add your own!

--- GnKoichi Asks a Stupid Question: Why do you say to take 2 drinks if Darkness and Heart are in the same sentence. Since we're already taking one drink for each of those words on their own, is this simple redundance, or are we now taking a total of 4 (four (4)) drinks? SuperSmash Master Retorts: It's because it seems like it wouldn't happen as much. It's like if he said "2 drinks every time someone uses the line "Sora, Donald, Goofy!" without any other words in the line."

You miss the point, SSM. -WVI

1 drink every time Goofy and Donald die in combat XD - ChaosTony
