Cyrano 

It is a situation when a nerdy guy helps a handsome guy date the girl that he loves by telling him what to say and what to do. The word is from a character that portrayed the act.

Our boss asked us to meet him here and he is not here yet, he just tried to put us together, he cyrano’d us. Let’s make him win, kiss me.

CyanogenMod 

A custom rom that's better than the stock rom.

I flashed CyanogenMod 10.1 on my Kindle Fire. It is so much better now!

It didn't take long for Apple to copy CyanogenMod and call it iOS 7.
