Some stupid thing made up by bored students still not back at school. Basically if you inbox somebody on there a number, they will write a status about you referring to you as the number you put, and supposedly the sender and the person doing the status update are only meant to know who it's about.
I preferred it when the birds put what colour knickers they were wearing on their status!!
And the last one wasn't too bad either. I think it ended up being about where they left their handbag at night but I assumed it was where they liked to have sex best!!
