University College London, the first college of the University of London. It was England's third university (after oxford and cambridge.)
It was not originally recognised by the Crown as it intended to (and still does, rather surprisingly) accept people of all races, classes and genders.
There is a long standing rivalry between UCL and King's College London (which is like this crappy bit of UoL, and basically is good for nothing apart from playing football with dead people's heads. The Wankers.)
UCL is a very cool place. Everyone should worship it.
UCL - An undercover lier. Usually referring to someone who is incredibly good at white lies or getting away with lies when they are in reality looked at very highly and even potentially a role model.
So I heard he's a UCL... Looks like he blew it huh?
Or
I wish I could be a UCL... I can't even make a believable white lie to my parents...
