Getting interrupted by your dog while being engaged in a sexual act with your partner.

Joe: "What happened last night with Mary? I thought you guys were hitting it off?"
Fred: "Yeah, the dog came in and well... canis interruptus."

Having sex once with someone you meet at a running event or race.

I met this chick yesterday at the race and after chowing down some free food, I had a one-run stand.
