“Yes, Pip,” said Joe; “and what’s worse, she’s got Tickler with her”
In this quote Joe is talking about the tickler Mrs. Joe uses to discipline Pip. The denotation of the word is quite friendly. Tickling usually being referred to as harmless or fun. But Dickens uses it an a sarcastic way using the connotation. Dickens is stating that the tickler is used to cause pain instead of laughter. People will see the tickler as something that would not cause harm but is actually uses in quite a bad way.
