A friend of mine and I were discussing a mutual acquaintance and my friend said, "Now, he's a real gazabo!" His pronunciation was like "GAZE-BOE." As he is one who likes to "test" me; I knew better than to challenge him. I replied, "I've never heard that word; how is it spelled?" He laughed and said, "G-A-Z-A-B-O."
When I went home, I hurried to find the word:
GAZABO: U. S. slang: a man or boy; guy or fellow ( from the Spanish for "a shrewd fellow")
It IS pronounced like GAZE-BOE and also like GUH-ZAY-BOE!
