Name of a disorder/disease?

I've heard of this thing were you always bite your nails and chew on other stuff. Has anybody heard of this and know what it's called? And if you have, do you have any information about it? thanks.

and by other stuff i don't mean anything nasty, just like pens and cell phone antennas & stuff like that.

it's called chronic onychophagia.

Cheweritis.

Tricky little beast.

hmmm...do you mean Pica? That is where one eats non edible items (dirt, paint, chalk, etc)

sounds like you have an oral fixation try putting a d*ck in your mouth

info:
Skin Picking is also called Pathological Skin Picking or Dermatillomania.
These disorders cause true distress. With Nail Biting will you see how nails will be bitten at continuously resulting in bleeding and sore fingers, at times even infected.
Those that pick their skin, will have mostly their faces but also bodies, covered with sores and scabs. The most insignificant flaw in the skin such as a pimple or blemish will be opened, picked at or squeezed, this by the use of their fingers or things such as tweezers, needles and so on.
The visual results of their behavior cause much shame and will make them cover up their hands and face, this embarrassment will go to the point of staying indoors to prevent being seen when they look at their worst.
The actions are either done automatically or to fulfill some need. These actions, in despite of what the results may be, do procure some satisfaction or relaxation.
The best treatment is Behavioral Therapy combined with medication which are the same anti- depressants ( SSRI's.) used for treating OCD and Trich.
Often Trich, CSP and Nail Biting co- exist.
The Difference.
When both disorders are found independently they do not seem to have any touching grounds.
Meaning that not all who have OCD are feeling sad or without pleasure and those who are depressed don't often seem to have the intrusive thoughts or rituals seen with OCD.
