To mentally mark your territory.
1. Carlos is mind pissing on Megan when Megan belongs to Dave.

2. Megan is dating Dave but Carlos keeps minding pissing on Megan.

3. If Dave and Megan were going to a party and Dave started talking to another girl when Megan was watching, she would walk over to Dave and mind pies on him in front of said girl.
