Do you engage in sport fucking?

From urbandictionary.com

3. sport fucking

1. The activity of having sex for the aerobic benefit. Also, athletic sex.
2. To keep a score card of the act of "love", what a playa does. It's the game that you hate and not the playa

1. I was sport fucking your sister when I threw my back out.
2. Last weekend I was sport fucking and I tapped your moms, your sister, your girl friend and her sister.

Personally I am getting too old for that shit. :)
