I didn't mean "Upper Coast", I implied Upper West Coast with my slash, which is a common referral to northern Oregon and Washington around here. Probably not clear in my reply.
Ah, understood. Where is "here"? I have literally never heard "Upper West Coast" in my life.
Eastern PA, Upper West Coast is what I've typically learned it's called. Interchangeable with Northwest Coast. To be fair, it's also normal to say redup; youse; jawns; werter; hoagie. Regional dialects are nuts.
