Dutch has a famously large set of rude verbs meaning "go away", and the list you and your coworker compiled is impressively complete. The core pattern is that most are separable verbs beginning with op- (opdonderen, oprotten, opflikkeren, opzouten), while others are fixed phrases (loop naar de maan, ga fietsen, scheer je weg). They all mean roughly "get lost", but they differ sharply in intensity, from mildly annoyed to deeply offensive.

Here is a practical breakdown by how likely you are to cause offence.

Mild to medium (common in casual arguments, not usually taboo):

  • Ophoepelen: the least aggressive, almost playful. "Hoepel op!"
  • Opzouten: salty but common, like "beat it".
  • Opkrassen, opdonderen, opduvelen: firm and dismissive.
  • Oprotten, optyfen, opflikkeren: stronger, often heard in angry exchanges.
  • Opsodemieteren: very rude but not usually a slur.
  • Moven: informal, from moven meaning to move, as in "move along".
  • Wieberen: to shoo away, often with a hand gesture.
  • Pleur op: imperative of pleuren (to throw), very direct.
  • Opbokken: rough, "get out of here".
  • Wegwezen: simply "be gone", can be neutral or rude depending on tone.
  • Scheer je weg: "shave off", idiomatic and dismissive.
  • Donderstraal op: from donder (thunder), colourful and rude.
  • Ga fietsen: "go cycling", a sarcastic way to say leave.
  • Loop naar de maan / loop naar de pomp: "go to the moon / the pump", old-fashioned but still used.

Highly offensive (taboo, avoid unless you intend maximum insult):

  • Opkankeren: derived from kanker (cancer). This is one of the most offensive words in Dutch, comparable to the worst curses. It is not just rude, it is considered uncivilised and can seriously damage relationships.
  • Ophoeren: from hoer (whore), also extremely insulting.

A few more you can add: opdonderen (already listed), opflikkere (variant), optyfen (listed), opzouten (listed), oprotten (listed), opkrijten (less common), opsodemieteren (listed), opdonderen (listed), opduvelen (listed), opkrassen (listed), opflikkeren (listed), opdonderen (listed). Also donder op, flikker op, rot op, zout op, hoepel op, sodemieter op, tyf op, kras op, duvel op, pleur op, donderstraal op, scheer je weg, wegwezen, moven, wieberen, opbokken, ga fietsen, loop naar de maan, loop naar de pomp, loop naar de hel (go to hell), val dood (drop dead), stik (choke), krijg de kolere (get cholera), krijg de tyfus (get typhus), krijg de pleuris (get pleurisy). Many of these are disease-based curses and are very strong.

Practical advice: If you are learning Dutch, recognise these but do not use them casually. The safest way to tell someone to go away politely is ga weg or wil je weggaan?. For a neutral "leave me alone", use laat me met rust. If you hear these in real life, context and tone matter enormously. A friend saying hoepel op with a smile is joking; a stranger saying opkankeren is a serious insult. When in doubt, ask a native speaker or check a reliable dictionary for register labels. Building this kind of nuanced awareness is part of reaching real Dutch Fluency, but you can start by simply recognising the words without producing them.

Next steps: Make a three-column list: mild, rude, taboo. Add example sentences from Dutch media or subtitles. Practise recognising them in shows like Undercover or Mocro Maffia, where street language is common. Never use the taboo ones in professional or formal settings. If someone uses one at you, the best response is usually to stay calm and disengage.
