The orginal meaning /usage of blag related to violent crime. These days you will find it has a far less sinister usage – it is now used more in relation to scrounging or obtaining something by deception … getting something for nothing. This meaning is far closer to the French word it originated from - Blaguer to tell lies.
Blag can also mean to talk persuasively, to bluff your way into a situation (a job,or a club) or to pretend to no about a certain subject. (interestingly Blaguer can also mean to tell tall stories).
