If you're referring to the technical, SMF-code side of things, then I wouldn't be able to tell you. But otherwise, no, custom titles have nothing at all to do with the monkeying system. They're assigned at whim by the admins (especially Goober) to call attention to some aspect of a poster's personality or history. It's most often the case that a user's title represents a particularly noteworthy achievement by that user, or an occurrence that that user was involved in...whether the noteworthiness be in the positive or negative sense. For instance, my own title doubles as both a cute literary reference and an allusion to a certain discussion I was involved in with another poster. (Ten points if you guess who!) There's some rather amusing history behind a lot of the titles, and those that are links tend to be the funniest of all.
