👉 Lilly pilly is a phrase that has become synonymous with the phrase "what do you mean" when used as part of a group conversation at a party, office, or home. It's often used to refer to someone who doesn't say what they really think or feel and instead resorts to saying something that sounds like a silly joke, such as, "I'm sorry, but I don't know what you're doing here." This phrase can be funny because it brings up the idea of "what do you mean" being used in a playful way. It's also unsettling because it implies that people who use this phrasing aren't serious or well-adjusted, which is a common negative stereotype of social awkwardness.
