The act of taking a laptop to the bathroom with you in order to relieve yourself after relieving yourself.

Fonterbate 

To "get off" on attacking and harassing someone in a chat room. To e-mail or to continuously "snert" someone in a chat room. Masturbating to the word's on a computer screen.

He sure loves to attack people who disagree with him in the chatroom. I bet he "fonterbate's" to it while he attacks them.
