Usually a clearly definable moment, when
coping mechanisms
devolve into chaos, fire and emotion, and your inner id is unleashed on the
perpetrator.
Commonly used in Australia, especially around idiots.
Example:
Dog walker to house guest: I'm sorry, I didn't realise the the afternoon walk was cancelled? Funny, because I came all this way? No biggie. Have a great day and I’m around if you need me.
Dog walker to Dog owner. If you ever cancel the walk at the last minute again I am dropping you as a client. Do you know how many dogs I need to walk each day? How many you have now inconvenienced? Do you think I need to put up with this? You need to take a long hard look at yourself.
House Guest to Dog owner: That
dog walker seemed nice. He didn't seem to mind about the last minute cancellation.
Dog owner to house guest:
Yeah, nah, he
cracked the shits.
