scenariorizing
When talking with friends, obsessively going over the countless scenarios that may happen with the opposite sex. Most often done between girlfriends, especially when a new relationship has started.
Mandy and Angela had spent all night scenariorizing about what she should do if Jordan invites Mandy over to his place. After 2 hours of discussion, they decided that if Mandy goes over past midnight Jordan will assume she is slutty, so she should only accept if he calls before 9 PM and she should wear tight jeans and a cute tank top, which is kinda hot, but not too hot.
