The act of making something shitty or horrible. The act of ruining/damaging something. Used instead of the word ruined or fucked up. This word is used to emphasis how bad things got, the Kitchen table wasn't messy, it was shitified.
Hip, trendy. A 'swankified club' would be one that all the cool people go to, that is a lot of fun, and that is basically just a really happening place. Swankified is a word used by only a select number of people, who truly understand it's meaning. The word is generally associated with the Oz Dust Ballroom- in fact, word has it that it's the most swankified place in town.
