A fling where one of the two involved turns out to be a clinger. Person #1 just planned on having a one time fling and person #2 is a stage 5 clinger.
"Man, I had a one-night stand with a girl on spring break and it turned out to be to a 'cling fling' -- she won't stop txting and calling me!"

Having a short-lived relationship with a member of the opposite sex, and they continue to try to make contact with you after the fling has ended
My fling with Kate ended months ago, but she keeps texting me and wanting to hang with me again! I guess she is my fling cling.
