Shag-Tag 

The process of shagging a male or female then tagging them in a social networking post in the morning after the deed is done, thereby making all social media aware that you have enjoyed sexual relations with that person. Pictures, videos and locations that can be added to the post make the shag tag more meaningful.

Have you seen the Shag-Tag on Facebook?

A game much beloved of students whereby the ultimate purpose is to end up in bed with a total stranger. As you do. Basically you turn up to the pub and get given a number (all blokes have even numbers and all girls have odds or vice versa). From this relative safety of anonymity you can leave a message up on a board, something of profound intellectual significance like "Number 31 you are really fit" or "fancy a shag Number 25?" Hopefully there will be so much booze going round that sex is inevitable, and you're guaranteed to wake up in the morning feeling slightly disgusted with yourself and quite possibly an STD. Great fun.

I went to that shag tag last night, ended up with the clap.

1. A game where the objective is to run around and catch the other person. Upon catching said person, the two of you shag. It's as simple as that.

2. A song by Prozzak.

We're all alone today. . .you up for a game of shag tag?

a shag tag is a simple question list or form that you fill out stating your sexual likes and dislikes. future bedpartners can use it as a manual so that you don't have to go through the annoying procedure of finding out all these things about the other yourself. actually, it's sort of a practical joke in most cases.

an example of a shag tag can be found in 'vrijages,' a recent collection of female erotica published in Belgium in 2006
