About What The Sigma Cat T Shirt
What The Sigma Cat T Shirt design started while watching comment sections fill with the same five words over and over. “Erm what the sigma” appeared everywhere, under gaming clips, on cat videos, in reply threads that made no sense. The designer, chronically online like the rest of us, noticed how the phrase evolved. It started as sigma male discourse, then mutated into pure absurdity. Pair it with a dorky cat? Perfect. Add the pointing hand emoji? Even better. The grey tabty in oversized glasses represents the exact energy of someone dropping “erm what the sigma” unironically in a YouTube comment. The distressed font gives it that worn-out meme texture, like it’s been screenshotted and reuploaded a hundred times. What The Sigma Cat T Shirt captures a specific moment in internet evolution, when words stop meaning anything and become funny simply because everyone says them.
