Slack (also known as float) is the amount of time you can delay
completion of a task without delaying the completion of the
project.  ...so if your project is 2 days long, then any 4 hour task
with the same start date and no dependencies would have 1d4h of slack.

What's not taken into consideration when calculating slack is the fact
that you've got resource overallocation in your example, which really
should be addressed before slack will have any real meaning.

Not off the top of my head... can you give some more detail?  What are
you reading and maybe an example sentence?  My only thought is that they
could be referring to recurring events or tasks.
