"verb (used with object) * to put into one's pocket: to pocket one's keys. * to take possession of as one's own, often dishonestly: to pocket public funds. * to submit to or endure without protest or open resentment: to pocket an insult. * to conceal or suppress: to pocket one's pride." I don't think the negative connotations are exclusively British. I've heard the phrase said plenty of times "John pocketed something", when it meant he kind of stole it. It's also used with regards to politicians sometimes.
