The 'Bold of You to Assume' meme is a popular linguistic snowclone and reaction template used to subvert expectations or respond to someone's presumptions. While it originated as a text-based retort on platforms like Tumblr and Twitter, it quickly evolved into a visual meme often paired with smug or defiant characters. The humor typically lies in the subversion of a positive assumption, such as 'Bold of you to assume I have my life together' or 'Bold of you to assume I'm a functional adult.' It remains a staple of internet culture for its versatility in expressing self-deprecating humor and sharp-witted defiance in any social media conversation.
