Rhyming Slang

Where does the word Geezer come from and what does it mean?

[Quizmonster]

It's not rhyming slang, but a corruption of the old word 'guiser', meaning someone in disguise or someone who goes guising. Guising meant mumming, as in performing in the ancient plays. It has meant 'old man' only since the 1880s.
