a casual almost dating kind of relationship. happens in the warm months of may-september when school is out! usually happens within summer workplaces where students hookup with each other all summer before going back to school in the fall. similar to friends with benefits, except these usually only last a couple of months before they come to an end due to the couple splitting off back to reality.
“omg did you and danny hook up all summer? where is he now?”
“he’s at college now. but he said he’ll come back to work again next summer. what a summer fling that was!”
"I thought you and him were just a fling? Why did you tell your crack-head uncle that your boyfriend moved away? ""It makes his ass stop asking me when I'll finally get a man-friend."
The act of leaving your boyfriend or husband while at a public venue such as a club or bar to go fuck a stranger you met and then return to your husband or boyfriend at that same venue a short time later.
Don't worry about my husband, he'll wait here patiently for me while I go flinging.
