Val. «Fer la mà»
This vulgar expression means to masturbate, to wank off, when talking about men. Another expression very usual in Valencian comes from this: ‘Anar a fer la mà’ (To go and make the hand), used in the imperative form ―Vés a fer la mà― is a vulgar expression of disapproval and annoyance, similar to the English expressions ‘Go and jump in a lake’, or ‘Go to hell’.

Of course, the degree of seriousness of the sentence depends on the tone of your voice, as many other expressions and interjections, for instance Xe.
