I've heard of a Klingon bar called Quch Quch. (The Happy Forehead). If I ever name a Klingon Dance Studio, it will be called cha' cha cha'. (It shows them two torpedoes). What similar funny names of repeating synonyms can you think up?
We could have a Klingon's repair shop called qoqqoq. (The so-called robot) That makes me smile.
A Klingon pet store could be called mut mut. I think it would specialize in vIghro'. Sorry if you are a fan of vIghro' hahaha
It's not perfect, but how about a Klingon race arena called chuyDaH chu' chu'chu' (He perfectly activates the new thrusters)?
