Although the original Freudian idea of the evolution of the character through various stages
like the "anal stage", at each of which it was possible to get stuck, has not really stood the test of
time, many outside the psychological community feel that it'
s still worth having a term for those backed-up individuals
one occasionally encounters who have an abiding need to stop fussing about something or other and relax, unclench, and *blow it out their
ass*. For this, "anally retentive" (or simply "anal") will serve as well as anything.
