Bankers Dozen 

Less than you actually wanted; banks will typically rip you off and rob you of your money, hence the term.

Chad:"Dude i told them i needed five pizzas at my house by 6 o'clock, and they only gave me four, and they still charged me for five! There was no time to get another one, fuckin' rip offs!"

Flynn:"Sounds like they gave you a bankers dozen bro".
