Crapophobia

If you know anybody who suffers from a fear of going insane, you'd best inform them to switch planets. To our existing, exhaustive list of irrational fears - which includes fear of sitting (cathisophobia), standing (stasiphobia) and urinating (urophobia); gravity (barophobia), the Sun (heliophobia) or rain (ombrophobia); hands (chirophobia), knees (genuphobia) and vaginas (eurotophobia) - we've added five new items to torment those unfortunate dementophobes until they find peace in the grave (which even cures necrophobes, by the way). Phobicphobia (the fear of fear) is just one of the asinine newbies.
