1. To talk extensively on a subject that you profess to have an in depth knowledge of, despite being wholly inaccurate and basing your argument on something that you once heard. Especially when; having being pulled up on your lack of examples or scientific basis for your argument, you continue to labour under the misconception that you are correct.
2. To consistently cause great annoyance by insisting that everyone be ready to leave at a certain time, only to be completely unprepared to leave on schedule yourself by at least 30 minutes.

Tiller: "Hurry the fuck up Colborne! We we're supposed to leave an hour ago you useless twat!"
