The word "farnarkling" has become firmly entrenched in the GOF family lexicon. From the verb "to farnarkle" it was coined in Australia back in the days when television pictures only came in black and white.
It means to waste time, fart around, or otherwise indulge in an unproductive occupation.
For a brief time it was frivolously redeployed as the name for a team sport where underwear was worn on the outside of normal clothing. This was however only a temporary perversion of its true etymology.
