5 Things you didn't know about Ronda Rousey

3: "Rowdy"

Rousey at the Mae Young Classic

It's no secret that WWE's newest signing is a WWE superfan. According to Rousey, her friends originally gave her the nickname but once she began to make a name for herself in MMA, she refused to use it, thinking that it would be disrespectful to the late great Rowdy Roddy Piper.

However, Hot Rod himself allowed Rousey to use the nickname after the two met.
