when u left your fly open, somebody notice a nut slip out into the open most likely it was a left nut...
nobody wants to say anything embaressing to that person, so its called a slip(a bad open fly)

honey, a man at work had a double slip today... maybe everybody should let people with slips know, so they dont walk around like that all day long in the office
