Penis Deficit Disorder, or PDD, refers to a condition observed, mostly, in women when subjects have a deficiency of vaginal, anal, or oral sex.

Syndroms of said condition include but are not limited to:
-Depression
-Anxiety
-Desperation for attention
-High irritability
-Crankiness

Often times subjects with PDD has been shown to camouflage their condition by insinuating them having PMS. This behavior is especially common among women who aspire to be feminists.

If a woman or a man showing such symptoms is encountered, it is advisable to approach them with caution. Men with PDD are considered to be especially dangerous to other men.
