Is there hidden meaning behind a double hug?

Anonymous
This is completely general, there's no personal reason I am asking. Let's say you're saying good bye to a guy/girl and you hug. Once you let go, they lean in for a second hug. This time the hug is long and comforting. So do double hugs mean anything? What if the hugs continue and lead to a third hug?
