an argyll ski slope is a classic event from scotland when a man or women would have to slide down a slope naked with various holes in it whilst erect men are underneath poking their penis through the holes.
When colliding with the "obstacles" the "skier" is penetrated and therefore is disqualified and covered in bodily fluid, which prepares the slope for the next rider.
this event is often abbreviated by frequenters to the A.S.S
Did you hear that Dougie came last in the Argyll Ski Slope on purpose?
Isn't that the 3rd year in row?
