If people would like a translation:

• Godverdeklere

A bastardisation which pulls “klere”/“kolere” - cholera - into “godverdomme” - god damn me. Definitely profane

• spreek Nederlands

Literally: speak Dutch. Not profane, though if someone does say it to you unprovoked, they’re probably racist.

• jij kankermongool

you cancer-mongol. Mongol in Dutch mostly is an insult to people who have Down Syndrome, not people from Mongolia. Definitely profane.
