Fancy a bouncy castle this weekend?

Bouncy Castle 

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.

Bouncy castle Catholics 

Catholic parents who, while no longer ascribing to the Catholic faith or ever attending mass will insist on their children receiving the sacrments of baptism, communion and conformation. So called because the event is more about the party that follows, which will always involve the renting out of a bouncy castle.

Tom and Julie are bouncy castle Catholics- you never seen them once at mass and yet here they are for their kids' communion.
