Answer

I would imagine that multilingualism would affect the vocabulary of a national language through borrowed words and code-switching. It might also affect word order in the national language.

Answer

It is originally an idiom from a song  "Don't worry, be happy.  Its meaning is to not allow problems to interfere with your life and smile through all of your problems.  It is a kind of feel good philosophy.    As for multilingualism,  I have no idea.
