The Why You No meme, also known as the Y U NO Guy, features a stick-figure character with a face of extreme frustration and outstretched arms. The character's face was originally inspired by a frame from the Japanese manga series Gantz, specifically from Chapter 55. It first appeared on Tumblr and Reddit around 2010, quickly becoming a staple of the Rage Comic genre. The meme typically uses 'text speak' and poor grammar to demand an explanation for a frustrating or obvious situation, making it one of the most enduring symbols of early 2010s internet culture.
