Do you pronounce it (Oo-Kee)
or (O-k)

I just pronounce it you-k

There was a thread about this a long time ago and the matter was solved.

"Uke" comes from the Japanese term "Ukeru", meaning "to receive"

Hence, it is pronounced in the Japanese way (Oo (as in Oolong) - K)

Already a thread of it. It's okay to bump threads in OffTopic as long as it is reigniting the conversation and not just a useless bump or spam.
