fi-fi bag

A sock or towel used in jacking off to eliminate hand to penis contact. Normally found in bunks in jail cells, boy scout camps, and tour bus bunks. They should always be handled with gloves or a stick due to the nature of the goo they normally contain.

Why are there socks in all the bunks? Don't touch them, they're fi-fi bags!
