Top Definition
The insanity caused by pregnancy. This exhibits itself in a spectrum of abnormal mental or behavioral patterns such as nesting, mood swings, pre- and postpartum depression, etc. In many cases, pregninsanity can be exhibited in some forms prior to an expected pregnancy and even after a full-term delivery. There is no cure for pregninsanity but those who come in contact with someone suffering from the disease should quarantine themselves by sleeping on the couch and ease their suffering by drinking lots of alcohol.
