I discovered a very useful word in Finnish today – hyppytyynytyydytys – which apparently means “bouncy cushion satisfaction”.
You can hear it pronounced on Forvo.
It breaks down as follows:
hyppy = to jump, leap, hop, bounce
tyyny = pillow, cushion, oad, bolster
tyydytys = satisfaction, gratification
I suspect it was made up for fun.
Bouncy (elastic, springy) in Finnish is kimmoisa, and a bouncy castle is a pomppulinna, which appears to be a brand name.
So if you were satisfied with your bouncy castle, could you say you have “pomppulinnatyydytys”?
What if you were dissatisfied with your bouncy cushion or castle?
Bouncy castles are also known as inflatable castles or jumping castles. The first such inflatable structures were made in the USA and known as “space walks”. What do you call them?
