As a Computer Science student, this is the kind of email I get:

Microsoft Student Flash - Discover Your Inner-Geek

What's an "inner-geek"? I know what an "inner geek" is -- he's the Dave that knows a girl is coming over, so he hides the 13 dvd's containing various re-edits of Star Wars -- but the hyphen just throws me off. Why the hyphen? What does it add?

It adds nothing!

It's all rather vexing.
