look up any word, like bae:
 
1.
the month subsequent to breaking up with someone during which the one who did the breaking up refrains from sexual activity with a third party unless the one who was dumped fucks someone else first
1. "Hey man, that chick wants your nuts. Are you going to bang her?"

"No man- I broke up with Leah last week and it's still her courtesy month."

2. "Dammit, Kristy just broke up with me and I heard she just got tag teamed by black guys!"

"I guess that whore doesn't believe in the courtesy month."

3. "Did you just fuck Jill? I thought you broke up with Kate two weeks ago. What about the courtesy month?"

"It's all good- Kate just blew the basketball team."
