When something angers Deirdre, she says that it “tickles [her] hate organ.” I absolutely loved that expression, which she must have stolen from some anonymous source. Later in the conversation, though, Amanda was tickling Deirdre’s feet, and Deirdre complained that she hates it when people tickle her feet. So we decided that Deirdre’s “hate organ” is her foot (or feet), and from now when something angers her, she needs to say that it tickles her feet.
