About us

Welcome to The Grumpy Ninja — where sarcasm meets T-shirts.

What started as a way to escape the 9-to-5 turned into a brand for those who prefer subtle wit, delayed punchlines, and a healthy dose of “meh.”

Our designs are for the introverts, the overthinkers,  and the "I’m silently judging you" crowd. If you've ever laughed out loud 3 seconds too late, you're probably our kind of person.

We're not just selling T-shirts. We're selling inside jokes, mood swings, and wearable sarcasm.

So yeah — join the grumpy side. It’s way more fun here.
