What's a Geek?

Gangly is a description of physical appearance and it means someone who's tall and thin with an awkward appearance in a clumsy manner. Geeks are interested or obsessed by things like computers and comics and science fiction that they're more interested in those things than people. Louis Theroux comes across as a bit geeky probably just because of the way he looks, maybe his sort of his English accent has something to do with it i'm not sure.
