For those of you not familiar (or need a refresher), 4chan released a password that allowed access to Sarah Palin's (former vice-presidential running mate to John McCain) email account. You can scout around for the original story, but the gist of it is that 22-year-old David Kernell used that password to hack into her account and was caught (by the Cyberpolice, maybe?).
Christopher "Moot" Poole (4chan's fearless leader and admin) was called to testify about the event since the password was leaked on 4chan. For whatever reason, both the prosecution and defense teams for the case questioned Moot about some common 4chan "slang," including "new fags", "/b/ tard", and "rick roll."
