Bifkin's Ridge

Same as gooch, the skin between the anoos and the ballbag. Would also be a great name for a movie.

biskini 

A bikini worn whilst skiing.

It was so hot in Flaine on the ski holiday that the girls had no choice but to sport a biskini on the slopes. None of the instructors seems to mind too much.
