51/50

The slang term “51/50” refers to a person who is mentally unstable or crazy. It comes from the code 5150, which is used to designate an involuntary psychiatric hold or involuntary commitment in California.

A 51/50 is someone who exhibits erratic or abnormal behavior, often indicating a severe mental health issue. This term is commonly used to describe individuals who are out of control, unpredictable, or dangerous due to their mental state.

Examples:
1. “Stay away from that guy, he’s a total 51/50. He was yelling and throwing things at people on the street.”
2. “I had to call the police because my neighbor was acting like a 51/50. He was screaming and banging on doors in the middle of the night.”
