All dictionaries I checked say that “sideways” means “towards or from one side”, but I have the feeling that it can also refer to “both sides”, for example.
When I pressed the orange against the table it squirted juice sideways (both to the right and to the left)
or
At my age I can only grow sideways (meaning that I grow fat towards both sides)
Is it correct to say so? If not, is there a better (single) word that can be used in the examples?
