That "don't begin to do silly things" is a very familiar way of suggesting, for example, not to have an affair or not to date other people in the mean while. Can also be just a way of talking, without a precise sense. The same of "I'll beat you". This is currently use by people for expressing a disapproval for a future behave. Does not mean, literally, you will be hit, is just a verbal "warning" said in a funny way
