one month stand 

when you see someone for couple of weeks or months, and when turns out that the person is really into you, you realize you have absolutely no feelings for her/him. the one gets a broken heart and you get an enemy. involves terrible moral hangover and everybody thinking you as an idiot.

"I had a one month stand with this girl and now her friends keep bugging me telling me how awful person I am."
