what does it mean when someone says much love to you?
It can imply a casual tone to show a friend affection. Similar to "Wish you well" or "Best of luck". In the two major parts of the U.S. it wasn't a very common phrase. And if it was used it was shortened to "Much love", "Much love, man" or "Much love, bro". It can imply a casual tone to show a friend affection.
