iming yourself

When you are bored and have no friends, so you start a chat with yourself.

benjabean1: hello
benjabean1: hello
benjabean1: how are you?
benjabean1: how are you?
benjabean1: fine thanks, how are you?
benjabean1: fine thanks, how are you?

Person walks by, looks at screen, "Dude, stop iming yourself!"
