thank u very much George , i see , go catch a flick means watch a movie ,but it is seemed that "Bob's your uncle" has other meanings in london , i'm not sure of that .

what does, "go and catch a flick" and "bob's your uncle", mean? Well "go catch a flick" means watch a movie and "Bob's your uncle" means someone named Bob is being associated to you as the sibling of your mother or father. :P
