A 'feature' of Windows XP and a type of Disobedient Computer Syndrome.

You can see a perfect example of this if you set the taskbar to autohide, and have say MSN Messenger running (and have disabled 'display alerts when a new message is recieved')

Whenever a new message comes in, the taskbar button for it will flash (or at least remain highlighted) until you click on it. As well, the taskbar itself will pop-up and you cannot get it to autohide until that button stops flashing (ie, you click on it to see what it is).

A *very* annoying feature as you might have several windows and programs running at once and may be focused on something which having to respond to a message (and seeing that bloddy button flashing like some attention craving person that refuses to wait for you and/or cannot understand that you're also doing other things and/or talking to other people) will break your concentration. Having busy or away mode will not stop this feature.

Pop-up's on websites and other windows demanding attention will also do it.

There is no apparent way to turn this feature off, making it one of the most aggrivating features in Windows XP.
A user is working in photoshop or watching a DVD with MSN set to away or busy when one of his contacts keeps messaging him, causing this wonderfull feature to distract him.

User: Hmmmm, looks like someone wants me to block him.

Very recent Canadian slang used when a person or a group of people get into trouble or an altercation and defend their actions by stating "but we had a bouncy castle". It came from the trucker convoy in Ottawa in 2022 when some participants excused their bad behaviour by stating there was a bouncy castle set up for the kids.

Used sarcastically when younger people get drunk and/or a party gets out of hand and the police show up.
Sorry Officer, we didn't mean to wake up the neighbourhood or cause any grief. We even set up a bouncy castle.
