When your mate repeatedly cancels on organised events which he has known about for weeks or even months with little or no notice, or good reason.
Nigel Wagner said he couldn't come to an organised 30th birthday party of a supposedly close friend who he lived with for a year, and by way of notification via a text message at 14:09 the day before the event. This is an extreme example of badmatesmanship.
