Ozooma is a different word from visitors.. Visitor is [dayef], visitors are [dyoof] both with hard d sound that doesn't exist in any language but Arabic :-D .. While a gathering (typically evolves food) means ['ozooma] I have to clarify that the last word is in many Arabian countries' accents, and is not exclusive in one accent... The standard Arabic word, which it's driven from, is ['ăzeema]
