You might use this to describe your dating schedule or your attic, unless you are unforgivably ugly and you live in a flat, in which case you’d have to think up something else to use it on.

It’s possible that the word has a quite unfortunate origin — it may have originally referred to the area where black slaves were once lined up on blocks to be sold. It’s also possible that it stems from maritime usage, referring to when a block and tackle were jammed against each other to stop the load moving.
