chuck off at (someone or something)

informal To mock, tease, or direct insults at someone or something, often by speaking sarcastically. Primarily heard in Australia, Scotland. A: "Nice shoes. Did you lose a bet or something?" B: "You can chuck off at me all you want, but I love these shoes." Please stop chucking off at the movie. You don't have to sit here and watch it, you know. Are you saying I have big ears? Wow, thank you so much for chucking off at me about it for the past five minutes.
