Bon Appétit is the French for 'Enjoy your meal'. It was also used in many other places such as the name of a magazine. But if you heard this or someone wrote it in an email or a letter, just know that it means enjoy your meal.
P.S. the following example is a real life quote that made me find and add this word in the dicionary:
Student:thanks for the meal today, believe it or not, today I
didnt have anything for breakfast and not much for dinner the night
before, so that muffins were quite satisfying. :)
And I never thought of a strawberry that deep in my entire life.
Teacher: No doubt there'll probably be other unexpected things this quarter, but
I don't know how many of them will be food oriented. "Bon Appetit" regardless.
Mum: Dinner is prepared you boys and I've spent all day getting it ready.
(the two boys sit at the table with the cutlery in hand salivating while mum finishes serving dinner)
Mum: bon appetit

"Base we've got some square groupers floating outside of Miami harbor."
A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.
