It's also not very well targeted at global reach. I mean, I assume it's a reference to something in some language / locale? Or, is the humor just super absurdist, i.e. they might've called it ShoeShoeEat and it would've been equally "humorous"?

Assuming the first, it simply means they never imagined being used by people other than (I guess) Americans. Which is unfortunate, but forgiveable.

It's also a terrible finger twister on the keyboard. I wish they swapped duck.co and duckduckgo.com so I could search on duck.co and find dev info on the fingertwister.
