The 'Chicken Tetrazzini' meme originates from a 2007 episode of 'The Maury Show' during a segment titled 'Whose Baby Is It?' A guest named Casandra delivered the iconic line: 'That’s why I’m with your man and you’re not, because he likes my chicken tetrazzini!' The combination of her intense delivery, the specific pasta dish mentioned, and the sheer audacity of the boast turned it into an instant internet classic. It is widely used to represent extreme pettiness, domestic 'wins,' or situations where someone is flaunting an advantage—real or perceived—over a rival.
