You post your own braggy stuff on someone's Facebook page pretending to be their friend or fan.
I posted on my teacher's Facebook: 'I love you.' She got 100 comments from students.
I posted on my crush's page: 'You are the best.' He thought I was his friend.
I posted on my mom's page: 'I am the best kid in the world.' She replied with a picture of me eating cereal for dinner.
