Buying someone something less for Christmas because they didn't buy you anything for your birthday or a past event.
Ex. Carl: "Hey Danny, can I have a beer, It's my birthday after all?"
Danny: "No, I already gave you one yesterday."
(Carl goes home)
John: "So hows it going?"
Carl: "Not too good. My friend's such a cheap bastard. I think this Christmas I'm a be Scroogin' a little bit."
Detesting Christmas, and all its related cheer.
Hey man, what are you up to for Christmas?
Wow. what an asshole.
