Facebombing - Leaving comments on someone’s Facebook wall when they forgot

Leaving comments on someone’s Facebook wall when they forgot to log out, and you pretend you’re them like you’re trying to trick them.

I logged into my friend’s Facebook and left comments like I was him. He thought I was trying to trick him.

I logged into my mom’s Facebook and posted comments like I was her. She thought I was trying to take over her life.

I logged into my brother’s Facebook and left comments like I was him. He thought I was trying to be his new sidekick.
