You might already heard this one but I didn't learn until a relatively recent internet meme that its only here in Norway that something being "complete texas" means its completely chaotic and messy.

Also I'm using "what the fir forest" ("hva i granskauen") as a replacement for "what the hell" and I have no idea where I've picked it up.. Nobody else around me do, not even family. Works just as fine though against pain and annoyances.

Funny my grandad had a little rhyme related to your ketchup effect:

"If you do not shake the bottle, none'll come and then a lot'll"

Clearly ketchup bottles have been a bigger influence on culture than we realised

Not really a saying, but when I was a kid I wanted to learn how to whistle so badly. I was told that if I ate pickles it would help me learn faster? I didn't eat any, and I still figured it out eventually.

A Dutch one I got from my Oma: "It's as if the angels upon my tongue have pissed". It means "yum".

My mom used to tell my brother's and I to eat vegetables that were longer than they are wide because it's good for growing an ankle duster.
