Irrationale Edit Meaning

1.

A rationale is a reason for something, usually a good reason, wheras an irrationale is a bad or irrational reason for something.

For example, a friend of mine was just telling me why I should use Ruby on Rails instead of Google Web Toolkit. She said it's because VCs won't like you to use technology developed by a big company like Google. Well that won't fly because she also said we should use GOOG Maps. Not making sense at all, quite an irrationale.
