What exactly is the Weak Nuclear Force?

What does it act on?  I have tried to get an explanation for nearly a decade, but all I've been able to glean is that it's responsible for beta decay.

I find it misleading to call it a force. The word "interaction" is much better. To me, "Force" gives me the impression that you can draw little vectors on particles or something, which is definitely not possible with the weak force. It doesn't attract or repel things. It just interacts.

For the rest, see Elektrophorus's explanation.
