mourning period

Following a break up, the mourning period is a phase of time where neither party is sexually active with another person. They also may not go on dates with other people. This allows time for both parties to reflect and recuperate upon their breakup. Normally this period of time is three weeks.

Boy 1: She showed no respect for the mourning period, she was fucking another guy before the week was out.
Boy 2: What a slut
