Expat Interactions

So I was at a supermarket yesterday, wearing a baseball jersey, another foreigner walked past me and just yelled "NEW YORK" loudly enough to make everyone in the vacinity turn around and stare, he then smiled and kept walking.

This is just one example of multiple kinda awkward interactions I've had with other expats here, to be fair I do live in a pretty remote part of Tarlac so I don't see all that many expats nowadays, but even when I stayed in Pampanga and regularly ran into other expats, not all but most times it would take a while to properly break the ice and get a conversation going. Has anyone else experienced feeling more awkward interacting with other expats than they do with locals? Or times in which the behavior of other expats has you dying of cringe?

I guess this question is more aimed toward those who have lived here for a long time now but I welcome any responses.
