Fennergy

Two twins (boys and or girls) who do everything in sync with each other and have similar personalities. They react to things similarly. They seem to have an "energy" between them.

Wow they just dodged a dodge ball at the same moment when they'er just a few feet away from each other!

You guys have this crazy fennergy between you guys!

Fenergy

The energy required to boost in My Sims Racing, for the Wii. Discovered by Dr. F, hence the name.

I lost the race because I didn't gather enough Fenergy!
