Leave-Behind 

When someone "casually" leaves an object or article of clothing in the home of a person they have just randomly slept with - thereby ensuring that they have an excuse to see this person again. Traditionally, the girl who just got slammed leaves her panties behind as a souveneer for the one who pleased her properly. panty,panties, boxers, bra, souveneer, wet panties, panties, her bra's on my ceiling fan now

I had to do another leave behind for Christine this time; because she kept my pajama tops last time as she cooed and said, they "smell like you" (oh yea , , ,).

Donna left her black g-string panties behind at my house, and George thought he should get them because he brought her over ! ! ! - - - ha!

A sweet Leave-Behind for the "Spoiler".

One night, I saw some dainty pink panties and a small bath towel on the sidewalk at Lake George! I think they were either a leave-behind, or a whicked gag.

Leave behind

When you take a dump and do not flush. This forces the next person that comes along to see your dump.

I did a leave behind at work today. Everyone was taking about it. It was awesome.

Bob: Well, I could just wait
Sara: Nah, I have plans with friends this week so I don't know when I'll be home
