But in instances where Australians have given New Zealanders the SHITCS, the effects of such an infection can be immediate and dramatic. And also pretty stink. Only this morning, several people collapsed frothing at the mouth in Queen Street.
The Ministry of World Cup Semi Finals has now issued the following diagnostic manual with a watch list of classic case SHITCS:
* Morbidity & Twitchiness
* Loss of Appetite
* Bi-polar score predicting
* Low level depression that results in a higher than usual Pineapple Lump consumption - unless you just lost your appetite (see above)
* Heightened sensitivity to sports journalism as well as Australian TV channels, accents, hairstyles or any adverts featuring cutaway photos of the top of Shane Warne's head.
It appears that a whole raft of previously mysterious illnesses can now be attributed to having a case of the SHITCS.
So far, no cure is known. Or available. The only alternative is to keep calm & carry on. And under no circumstances are you to give any Australian you meet the bash.
Hopefully, that will happen on Sunday.
