The 'Bad Teacher' or 'Are You Ready for Your Lesson?' meme typically features a teacher-themed stock image or a scene from a parody video where an educator stands before a class or chalkboard. It is used ironically to introduce a 'lesson' that is either blatantly obvious, incredibly niche, or intentionally bad advice. The meme gained traction in various internet subcultures as a way to 'school' others on specific topics ranging from complex coding problems to social faux pas. Its versatility lies in the contrast between the authoritative setting of a classroom and the often absurd or humorous content of the actual lesson being presented.
