ELI5: In U.S. political debate, what does "globalist" or "globalism" mean?

This is a term that's been in the news a lot lately, but I'm not sure what it's supposed to mean. Usually it's placed in opposition to "nationalism" and "nationalists," but it seems to be more than just "the opposite of nationalism."

Globalisation is the phenomenon where increasing free trade and ease of international travel makes the economy less and less local. It is based on the theory (it's essentially proven to be true) that tax-free borders benefit both countries and is true of every two-country combination. It's problem is that some individuals in both countries lose their jobs, as people in the other country are either better or cheaper at it. 

For example Costa Rica is better at Banana Farming than America, but America is better at building computers than Costa Rica. This means American Banana farmers lose their jobs to Costa Rica, but America gets all the Costa Rican Computer manufacturing jobs.
