When a friend or acquaintance has a different personality every time you see them. People with IPD will act different every time you see them. You never know what type of hello youre going to receive when you run into them.

Run in 1: "Yo I just saw Stephen at the wedding and he barely dapped me up. He acted like we weren't best friends for 10 years. He must have Inconsistent Personality Disorder (IPD) "

Run in 2: "Yo I just saw Stephen in the park and he gave me a massive hug and started to reminisce about high school. Its funny because last time he barely acknowledged me. He for sure has IPD."
