vagina poisoning
When a male ditches his friends and family over a vagina because he has been poisoned by said vagina. Symptoms include sudden disappearances, ignored phone calls and texts, utter denial of vagina's ugliness and wrongdoings, and psycho babble about how great the new vagina is. Although this is not contagious, it can be harmful to all those who were close to the male suffering from vagina poisoning. Almost all cases of vagina poisoning have been spawned by a succubus.
