I'm Flemish and I use it a lot, actually. "Dat kan mijn reet roesten.", it has a great ring to it.
At least in Amsterdam we use the expression like this.
And although I too only know the expression with the word "aan" in it, the translation by jauco at the start of this thread seems to suggest they also use it without that word.
What is actually the Flemish expression for this? "Den boom in" (=up the tree) is the closed one I could find.
