Here’s how you do it:

• You see a placename on a signpost.
• You come up with a definition for that word, using it to describe a concept, feeling or thing that currently has no word attached to it.

Here are some of my own examples. These are real Australian placenames. You’ll get the idea.

Goondiwindi:
A small embarrassing fart unexpectedly expelled when laughing out loud in quiet company.

Ardleton:
A person of advancing years who drives at a speed so slow that they could possibly pass away before they reach their destination.

Barrogan:
A frustrated person who is in a hurry to drive somewhere quickly, and who is being prevented from doing so because they are stuck behind an Ardleton.

Conway:
A road that you drive down for a considerable distance before you realise that a prankster has in fact turned the sign at the last junction in the opposite direction.

Hindmarsh:
An inviting patch of lawn which appears to be dry and the perfect spot for a picnic, however, after sitting there for an extended period you discover that your bottom is actually wet.

Bangalow:
A car which has had its suspension lowered so as to increase performance, but which is in such a decrepit state of repair that you wonder why the owner would bother in the first place.

Andover:
The act of hanging around for as little time as possible at a car dealership when you trade your old car for a new one, knowing that the old one is on its last legs and will probably never start again.
