it was moderately post ironic for us, when we used it. It went from being a once in a while thing just to add some additional slang. To a post hyper irony period where the joke is that the words we used dont make any sense and have no meaning, therefore you can just do that with EVERY word.
At the time, I was too busy glaring at the concept of irony being used incorrectly to know any of the slang you are referring to.
