Inability to remember agreeing to attend events, work overtime, go to a party, often due to effects of drugs, alcohol, better plans came up, a fight with your girlfriend, or you simply don’t want to put on pants that day.
You said you would help my friend Katie move today! Sorry Babe, I must have planesia.

Why did I agree to go to the dmv with my mom today???? Hey-just say you have planesia and forgot.
