Fenerty 

The sexual act of knocking one's partner out with a hard, blunt object and proceeding to hold them upside down and, upon climax, ejaculating into their nostril.

Aw, you gave her a Fenerty?

Yeah, she was out for an hour!

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!
