You can get this for your girlfriend as long as you do it tactfully.
Possible lines to use to disarm the situation:
"Hey babe, I just bought We Ski, let's play!" (Then casually leave the Wii + WiiFit + WiiFit software over at her place that night/weekend).
"I just bought this WiiFit, but I'm bored with it. Do you do yoga?"
If she senses what's going on, get indignant and tell her that you think she looks beautiful and you can't believe she thinks you would stoop that low. (Then take the WiiFit back to your place and wait for the apology call.)
