- "What the hell does 'kree' mean?"
"Well, actually, it means a lot of things. Loosely translated it means 'Attention', 'Listen up', 'Concentrate'."
"'Yoo-hoo'?"
"Yes, in a manner of speaking." - ―Jack O'Neill and Daniel Jackson[src]
Kree is a very common word in the Goa'uld language. Its meaning appears to be circumstance based, but it is roughly translated as "attention". (SG1: "Children of the Gods", "Point of View")
