I was amused by the Wikipedia definition of Bogle.

The Bogle is an ancient Scottish mythological creature that has a nasty temper. They are reputed to live for the simple purpose of torturing young children that disobey their mothers, or of punishing those that are lazy, incontinent (lacking self-restraint), or guilty of crimes.

The Bogle is also a creature that loves to vex humans till they go insane! They may cause a human to hear a voice around a corner, only to find that nothing is there, and then repeat the same antics around another corner. This will go on and on until the human decides to give up in utter frustration. Another way they might annoy humans is to enter a person’s house and create a mess, make weird noises, or do other small things that for some reason, always happens at very unopportune times.

The people who know me will have to say how well the definition applies in my case! (The mess part at least may be true. )
