The artful
dodge of putting down an activity
someone finds an interest in. There's an implication that there's something
wrong with the person who likes the activity, but because it's not spelled outright, there's plausible deniability.
Person A: I don't get why people like sportsball. It's so boring.
Person
B: You're humbugging me because I like
baseball?
Person A: I didn't say you're bad for liking sportsball...
Person
B: No, but there's a strong implication there.
