flings?? busy schedule

Do you guys know the meaning of fling? Haha
This two month I come across this problem. Guys are asking me to be their flings.
I’m totally not interested in this type of complicated relationship.
To me, I would explain this “fling” by two meaning.
If attached guys ask to be their fling, mean—they just want to get from you whatever their gf don’t give it to them.
If single guys ask to be their fling, mean—the girl is not up the standard to be their gf.
So simple ..so girl..don’t be a fool and fall into their trap.
Haha
I realise I have change, I become more negative and defensive in relationship.
What had happen to me..?
No more clubbing from now onwards, I need a break.
