I've just been informed the Norwegian phrase for speed bump also describes me to a T
@mathowie @DavidBlue Unfortunately the sign is wrong, and the correct word is "fartshump" (singular) or "fartshumper" (plural). "Hump" is upwards, while "dump" is downwards, but for some reason a lot of people are using the wrong word when it comes to speed bumps.

Edit: Since I can't see the road, I can't really know if the sign is wrong or not, I guess there might be downwards dumps to regulate speed on some roads, ofc, but mostly they go up.
