A 'bucket list' is a list of things that you intend to do before your body ceases to function and you are forced from the physical realm.

Fun fact: The "bucket list" comes from an Irish figure of speech which is to "kick the bucket". To kick the bucket when used casually means to die but more literally it means to commit suicide when you kick the bucket you're standing on to land in the rope wrapped around your neck. So the "bucket list" is actually a list of things to do before we hang ourselves, or "kick the bucket" so to speak.
