A longer than average dating fling. When your casually dating someone for about 6-10 months but the relationship still never turns into anything serious. You may take this person to a movie or a friends wedding all while maintaining a highly sexual relationship but then the fling sort of just ends without any bad feelings.

"Dude, if Sandy doesn't let me flong her tonight, I'm dumping her.
