The 'I Want a Baby' meme is a popular comedic format that plays on the subversion of expectations during a conversation about the future. Typically, the meme features one person expressing a desire to start a family, while the other character either reacts with shock or offers a humorous alternative, such as a 'baby' version of an object or animal. It has evolved through various comic strips and image macros, becoming a staple on social media for highlighting the contrast between traditional life milestones and modern personal interests. The meme is frequently used to joke about expensive hobbies, pet ownership, or the general chaos of adult responsibilities.
