A serious condition in which a man forgets the existence of his genitalia, specifically, his testicles. The onset of this disease usually occurs under certain circumstances. When a man is in a relationship in which his every move is controlled and dictated by his partner, he is said to carry the main symptom of Ballzheimer's Disease. During social activity with others of his gender, the victim is said to regain his lost balls, however, once his partner returns or makes her presence known, the victim quickly relapses into having Ballzheimer's. This disease is usually observed in one sided relationships, where the woman is dominant.
"Hey, what happened to John last night? We were at the bar and he got a text from katie, then left frantically saying he was gonna miss the grey's anatomy marathon."
I worry about John. I think he's developing Ballzheimer's Disease.
