figidy
More of a feeling than a verb... but it means you are getting wild, crazy, and drunk. All of the above have to happen, you are not only getting drunk but you are being a wonderfully awesome version of yourself. Pretty much just living life how you want to and not worrying about what others think.
*at the bar* "Look at that girl over there drinking a margarita. I wish I was having as much fun as her, she is definitely getting figidy tonight."
