When the outside temperature is so low that all bodily fluids that leave the body freeze quickly. Therefore when mucus leaks from the nasal passage and freezes it forms a stalactite from the nostrils.
When Harry and Lloyd were driving to Aspen on a skooter without the necessary protective clothing for Aspens climate, snotsicles formed around their nostrils.

I had to stop and wipe away snotsicles every five minutes while shoveling snow after yesterday's blizzard.
