A bot that uses a standard series of responses to what you type. Invented by nerds so they can chat to an 'imaginary friend'. Also used to keeped someone on MSN busy (if you don't like talking to them).

n. Also known as a "chatterbot," these are AI programs designed to simulate "intelligent" conversation with human users. The problem, with most of them, is that either a. they sound ridiculous, or b. the programmer has tried too hard to make them "human." Either way, most users try to get them to talk dirty. Among the most famous of these are ALICE, ELIZA (the original), and Cleverbot.
