flipping or freaking out; yelling or talking with a specific tone in order to annoy, anger, etc. to bring your point across because they did something wrong or are doing something wrong; making any action because you are angry or upset.
My mom was aflippin last night because she found out I failed the quarter. My girlfriend was aflippin when she found out I was cheating. The crowd was aflippin during the protest rally.
