It took me several days and a mini melt down to figure out how to do that. Finally on Monday after going back to Learn Ruby the Hard Way exercise 12 I realized that all you have to do is open a new whatever.rb file and require the gem then you can screw around with it.
I looked up documentation on the abbrev gem. Here are some good links:

I called the method .abbrev on a the string "elephant" and it returned:
eelephantelephanelephantelephantelephanteleelephantelephelephantelephaelephantelepelephantelelephant
broken into lines it looks like this:
e
elephant
elephan
elephant
