permashrink 

The condition of one's genitalia after extended time in a cold place, usually Alaska. Unlike shrinkage, permashrink will not go away until one has moved to a place of normal climate.

Guy 1: Dude, I went up to Alaska last month, it was sweet!
Guy 2: Oh I'm sorry man, you must have had some crazy permashrink.
Guy 1: Yeah...I almost forgot I wasn't usually the size of a newborn baby.

Permashrinkage 

Some one from Canada, usually has a small penis. Comes from the shrinkage that happens to the penis from the constant cold of Canada.

Kyle is from Canada and has a small penis, therefore he is a permashrinkage
