Throughout the course of Harry Potter's time enrolled as a student at Hogwarts, one of the main issues he dealt with was an annoying bully. Draco Malfoy loved bullying Harry because he was always so insecure in his own skin. Tearing someone else down to make himself feel bigger and stronger was Draco's way of thinking.
Of course, Harry faced off against much greater evils during the franchise (like Voldemort), but the inconveniences Draco brought to his life were still apparent. Draco remained unlikable for the majority of the franchise for his immature quips and terrible behavior. His bad behavior was rarely ever called out by others, which made him believe he could continue acting up without any repercussions.
These funny memes shed light on the fact that Draco was never really that intimidating and that he probably should've lost his status as Harry's bully much earlier. Harry's time on campus would've been a lot smoother without Draco in the mix!
