Please Don't Bully Me, Nagatoro (Ijiranaide, Nagatoro-san) originated as a web manga by Nanashi before becoming a viral anime sensation. The meme typically centers on the dynamic between the sadistic yet playful Nagatoro and her timid upperclassman, Senpai. It gained massive traction online due to Nagatoro's wide range of expressive facial expressions—most notably her smug and 'sus' looks—which users repurpose to mock, tease, or highlight awkward social situations. From the 'noodle arms' animation to her iconic verbal jabs, the meme serves as the ultimate template for lighthearted trolling and capturing romantic tension within the anime community.
