You could try the Klingon Language Institute at kli.org but it seems to be down at the moment. Must be the government shutdown.
Klingon politicians would battle each other to the death in single combat, then fix the budget. Then more battle. .
No doubt it's something that sounds suspiciously like "Ben & Jerry's" as shouted by an angry, seriously constipated person.
Curious. The Klingons had no word for Peace Maker, in all of their long and storied history. They only eat food as it's still alive and yet ... they can be expected to have a word for Ice Cream?
I don't remember the actual Klingon word(s), but I think it roughly translated out as "a warrior's goop."
As of yet, there is no known Klingon expression for "ice cream". You might describe popsicles as nIm taD naQ(mey) ("frozen fruit juice stick(s)") and soft ice cream as tunbogh nIm taD ("frozen milk which is soft"). vaj HuH = "warrior slime" vaj chatlh = "warrior soup" (or "warrior nonsense")
Klingon ice cream comes from the mammary glands of a adult female Targ. Milking a Targ by hand come with a four percent fatality rate. ^(oo)^
There must be a word for it, because in the TAS episode "Practical Joker" the virus also affected the Klingon ship. They were heard to be furious that their food synthesizers were throwing out desserts, including ice cream sundaes (or some sort of ice cream-based dessert).
