Continuity mistake: When the table of the iCarly gang falls over due to Sam's fight with the bully, Gibby's phaser falls on the floor without a scratch. Moments later you see the phaser when the bully stands up again, all messed up.
Answer: In direction translation it means 'Mischievous Spirit'. 'Hob' as in HobGoblin means clown or prankster, and 'Knocker' was an old age term for Poltergeists in mines. Miners would often complain of hearing knocking sounds down mines when there was no-one else down there, hence 'Knocker'. It's not a regular English expression though.
