Jun 24 Word of the Day
An exclamation made when your friends or family are teasing you to a point where you can't handle it anymore and a hissy fit is in order.

Derived from a YouTube user's famed outburst following Britney's lackluster performance at the 2007 VMA's.
Sarah: 'OMG Susan, I can't believe you are wearing the same skirt as yesterday. Oh, and by the way, EVERYONE knows what you did with Kevin on the weekend. Plus you look a little fat, are you retaining water?'

Susan: 'LEAVE BRITNEY ALONE!'

more than 50% of the people belonging to a Catholic Church Parish that only come to mass on the big holidays- Christmas and Easter-therefore making it difficult to find seats because the Church is overpacked.

Joe: My mom is making me go to the early morning Easter Mass even though i haven't been to Church since last Christmas.

Kevin: You are such a chreaster.

Someone who only goes to church on Christmas and Easter. Your typical everyday Christian who tries to act all holy twice a year when the relatives are in town. In reality they couldn't be more of a scumbag. When mass is over they go back to getting drunk and beating the family dog.
Frank: For the love of god Dorothy do we really have to go to church?
Dorothy: Frank it's Easter, everybody goes to church on Easter.
Frank: I don't give a rats ass I'm not going.
Dorothy: But we haven't gone since Christmas Frank.
Frank: Fine, then go you god damn Chreaster.
