While listening to the Grammar Girl podcast yesterday, I learned about a new punctuation mark. Honestly, I don't know how new it is, maybe I wasn't paying attention in class that day.
It is called an interrobang and is used in suprised questions. For example ...
What‽ You won the lottery‽
The name makes sense to a computer geek, as it is an interogerative and the "!" is called a bang in unix (computer operating system and C programming) speak.
