Facedancing - Using someone’s Facebook to post stupid stuff and laugh when

Using someone’s Facebook to post stupid stuff and laugh when they find out. Usually happens when they leave their account open on a public computer.

I posted 'My dog eats my homework' on my dad's page. He had a meltdown.

I used my neighbor’s account to say 'I beat my dad at chess.' He came to my house with a broom.

I logged into my mom’s account and wrote 'My kids are smarter than me.' She texted me 10 times.
