What does:

::: d & r :::

Ducks and runs.

(i.e. says something humourously controversial and scarpers)

Since we can’t make anonymous posts, I do not understand duck & run. I have made such posts myself, but always with the knowledge that I can run, but I can’t hide.

See this thread for more.

I don’t think it’s about hiding. It’s about saying something that might be considered rude or trollish but with some indication that it’s a joke.

Doesn’t usually add a lot to a thread, but then again this’d be a boring place without humour.
