1— Iemand bij de neus nemen
Taking someone by the nose

This seems like the English "to pull someone's leg" or in Spanish "to take someone by the hair". I find it funny because here in Latin America we have the stereotype of European people being long-nosed, so to each their own stereotype-based worries.

2— Het bijltje erbij neergooien
Throw down the axe

From the text, the first thing I thought was "to surrender", "to give up". But from the image, I thought it was about asking someone for their hand in marriage.

And from the meme perspective:

Maybe the Dutch have a Dwarf line of thinking and go throwing axes at projects they want to join.

3— In de soep lopen
Walking in the soup

I would imagine it's someone in some kind of trouble or intense situation.

Ex. "I'm knee deep in the soup and your asking me to blow up balloons?"
