Much like the tooth fairy, this little creature comes to men around the age of 12 and blesses the poor soul with hair on his taint. After many years this fairy will come back and shave the region for a few nickels placed under his pillow.
Young boy: Dude the grundle fairy come and put hair down there!
Older man: Dude, this fucking grundle fairy better come tonight cause I keep getting god damn dingle berries in my taint hair and if I shave it I usually just cut my balls up.
