"That's dumb, you're dumb" is a free Chrome add-on developed by Odin! It falls under the category of Browsers, specifically Add-ons & Tools. This add-on is inspired by a quote from the YouTube video "Dark Souls: In Summary" by PlagueOfGripes, specifically the line spoken by Kaathe at the 2:50 mark.

The add-on's main purpose is to inject some humor and entertainment into your browsing experience. It does not have any specific functionality or features beyond displaying the phrase "That's dumb, you're dumb" in various contexts while you navigate the web. It is important to note that this add-on is not affiliated with the original video or its creators and is meant purely for amusement.

If you're looking for a lighthearted and quirky addition to your Chrome browser, "That's dumb, you're dumb" might be worth a try. Just keep in mind that it does not offer any practical utility and is purely for entertainment purposes.
