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."
