A princox is a self-confident young man. Meaning TOO self confident
Capulet calls Tybalt a "princox". The OED says it means "a pert, saucy, boy or youth" which you can get from the context. It also says it means the same as a "coxcomb" which suggests that it comes from the strutting, arrogant behaviour of roosters.
Mister Capulet (father of Juliet, and head of the capulets) was calling hot-headed Tybalt a princox because Tybalt wouldn't listen to Capulet and just wanted to kill Romeo.
He says, "Go to, you are a sucy boy", and calls him a princox.
When he sees that Romeo is at the party, he sends for his sword right away, without even checking with the host of the party. It was impulsive and downright rude. No wonder Capulet called him a "princox".
