A list of people that, if you could, you would slap for doing or saying something stupid, shady, unrealistic, or being unnecessarily dramatic.
My boss waited until the last minute to give me a project and now wants me to cancel my trip. He is now number 1 on my slap list.

Person 1: I went to Subway and asked for a veggie sub and the lady asked me if I wanted lettuce.
Person 2: Put her on the slap list.

More commonly used as "the list".
