AutoInsult is a fun little program that generates insults for you in a variety of styles. It then copies them into the clipboard (as text) so that you can paste them into emails, documents, or wherever else a good insult might be needed. You can also get it to pop-up an insult at regular intervals.
All the word resources are stored in an external file, which allows new dictionaries to be "plugged in". Currently dictionaries in both English and American English are supplied, containing 4 styles (Arabian, Shakespearean, Modern and Mediterranean).
AutoInsult will amuse most people, but may offend others. It is not, however, obscene or vulgar. Additionally, the program starts out with the more offensive styles disabled by default, although these can easily be enabled via the options menu.
