What is Typejack?
1.
When typing into an IM window or webpage text entry field and someone IMs you and a window pops up that automatically takes the focus of the screen. When this happens, the last 5-10 letters are typed and sent to the IMer instead of where you wanted. For some reason, this always seems to happen when typing passwords, and the person who originally IMed you receives "b0n3r!" or something similar.
"I was trying to log into my bank account when Dave typejacked me, now I have to change my password dammit!"
