OPA
OPA is a Greek Word that may be used as an ‘Exclamation’, or ‘Utterance’, or ‘Declaration’, or ‘Affirmation’ or a lovingly gentle way of telling you to ‘Stop’ ... depending on the situational context.
It is a word or pronouncement of celebration; the celebration of life itself.
It is another way of expressing joy and gratitude to God, Life, and others, for bringing us into the state of ultimate wisdom; that all that really matters is health, family, and friends.
It is a humorous affirmation that you’re the best; that you’re where you’re supposed to be; and that you need to stop and celebrate. …
It is the Greeks’ way of stating they have come to a level of serene exuberance able to enjoy life as children. … In a state where having been fed, and having quenched our thirst, and having enjoyed the pleasure of uniting with others, we have filled with hope and confidence that life abounds with all that we need, … and that food will always be there, … and so, we break the plates, … because tomorrow there will be more. … And we light a fire and dance around it as a symbol of the warmth that surrounds us. … and …
<br><br>We break the plates as a way of saying thank you to those that helped us reach a state of celebrating our life, … as a way of saying thank you to the music that brought peace to the world, … and we break them to honor the one that’s dancing, as we kneel in front of them and look up to them exclaiming : Oooopa !!! …
And we throw the napkins in the air as a reminder that we are as free as the birds; ‘sky is the limit’ … so ‘Let go, Be Greek, Fear nothing and join in the celebration’.
It is a way of saying “don’t worry” … no matter what has happened you are still alive, … “don’t be harsh on yourself,” there’s another minute and another day ahead of you to right what’s wrong, … and we are here together to make sure of this. … So, as an example when someone accidentally drops and breaks something, no matter how valuable, we yell: Oooooopa !!! … kind of “It’s ok,” … everything can be mended if your mind is healthy and still open to music, dance, mezedes, and wine !!

Somebody dropped something, or broke something : Opa!
Someone is assisting someone to back up the car, ...and just about whene the driver is about to hit something : Opa (ie : Stop !)
Somebody is dancing and another is breaking plates as they exclaim : Opa !!
A group is drinking and as a form of Cheers : Opa !
