` ok a direct quote from the page for fuck is ``Other uses are dysphemistic: The sexual connotation, usually connected to masturbation (in the case of ``go fuck yourself`` or ``go fuck your ass``) is invoked to incite additional disgust, or express anger or outrage. For example, ``Fuck that!``, ``Fuck no!``, or ``Fuck you!``.``  thats a bit worse than saying ``masturbation is like taking a good dump`` mate come on just put it back up and quit being a douche...`
