Is the BBC referred to as "auntie"?

Yes. Not absolutely sure why. I think it is meant to imply a kindly but rather prim and proper manner.

During that show, Bonnie Greer said something to Nick Griffin that I interpreted as "toot toot", but which I read in an online article as
"2:2". I gathered that it referred to the number of years a person attended a college or a university. Is that correct?

University degrees are awarded at either Pass level or with Honours. Honours are subdivided into First, Second and Third class. Because most people get a Second Class degree, this is further divided into 1 and 2. Hence the possibilities are 1, 2.1, 2.2, 3, Pass. People with a 2.1 look down on people with a 2.2 probably to make them feel better about not getting a First.

A 2.2 is also known as a Desmond. Say it out loud.
