Used to describe an excursion, mainly to an eastern european country, where the sole purpose is to sleep with several whores and local sluts over a few days. Often undertaken on the pretext of a 'stag holiday' or 'cultural team building exercise' by 40 something men who cant afford the homegrown offerings advertised in phone boxes.

Steve: That just sounds like a whorliday to me.
Jim: Well thats basically it, yeh.
Steve: Count me in, I well fancy offloading up the pipe of an ex-commie.
