The Chocolate Joke is another chat-based phenomenon.

The Chocolate Joke was sparked on 28th December, 2006, when the chat was making rude innuendoes about Mello loving to 'lick and suck his "chocolate"' and so forth, with 'chocolate' being an obvious euphemism for penis. This is regular chat interaction, but this gained fame at the expense of Tifa-mun, who missed the innuendo entirely and had to be flat-out informed of the joke.
