Japanese "ojisan" and Arabic or Russian exclamation.

Pretty much, what I'd appreciate some help with is the way the Japanese word "ojisan" might be used with a proper name, similar calling someone "Uncle Dave" in English. If this would be altered in referring to a close male friend of one's parents rather than a blood relative, that would apply.

The other thing I'd like to be able to find is an exclamation of surprise in either Arabic, Russian (those two preferred) or Japanese. Something that might make sense for a situation such as the passenger of a car being started by the driver suddenly slamming on the breaks.

Transliterated, if possible. Thank you.
