uncuffed
Uncuffed means that you are single and free to be yourself.
My girlfriend broke up with me yesterday so I'm officially uncuffed and ready to P-A-R-T-Y!!
Uncuffing season
Usually during the spring and summer months when people who were previously in relationships during the winter break up with their girlfriend/boyfriend to be free for the summer and warm months so you can play the field and not be tied down during the best times of your life.
Jake: "Dude it's uncuffing season, you gotta break up with Jess."
Justin: "I know bro, I will boutta hook up with Sam and Jane."
