Disgusting Habit

You develop a disgusting habit, notion or mannerism that sets you aside from normal people. Cannibalism, a refusal to eat anything but red meat, constant drooling, severe drug abuse, some disgusting compulsive behavior, or some other very extreme habit. You can keep up a semblance of normality for a short period of time, but never for long.

If you want to have several disgusting habits, later habits must be even more disgisting.
