When you are dating a chick and know its going down hill so you bang her and then dump her the next day.
"Are you and that chick breakin up soon?"

When a male finds a partner (usually a cheap hooker) and takes them to a motel/hotel and rents a room on the top floor. They proceed to have sex, and during sex, the man secretly inches over towards the window while still having sex. He then places the girl belly down in the open window frame and does her "doggystyle". When he is ready to finish, he speeds up, splooges, then quickly pushes her out the window. It is favored by many because it allows you to finish inside your partner and not have to pay a single penny, but do this act with caution, as it IS MURDER.
