in the uk we have two universities that are considered two of the best in the world
they are oxford and cambridge
they are referred to, collectively, as oxbridge.
when you apply to university you are only allowed to apply to one of them, to cut down on competition for the top universities.
in the film batman and robin, when batgirl comes to stay and she's like batmans niece or whatever, alfreds all "she has just arrived from oxbridge university"
this was actually my face when
