three man skiing 

The action of one person sitting in the middle of two erected males and imagining themself skiing down a fast twisty hill using the male's erections as ski poles.

Yesterday, it was cold out so we decided to do some three man skiing inside. After I hit a jump a couple of times, there wound up being an avalanche.
