A fiendshadow is a deviant and will often engage in sexual intercourse with people, especially its teachers, i.e its driving instructor. When it cannot engage in sexual intercourse, it watches copious amounts of Japanese porn (hentai).
Fucka Fiend (short for fiendshadow in many cases), he fucked my driving instructor Ira!

Get the Fiendshadow mug.
To fiendishly shadow is to watch hentai for over 48 hours, and only stopping to eat. Frequent fiendish shadowers will often become fiends, and will normally be morbidly obese because of the nature of the activity.
Wow, fiend was actually fiendishly shadowing last week. I thought he was just sick, but he still smells like cum and pizza.
