I don't think the term is all that common today in the US. But, counter my pervious comment (though I hadn't been active that day and it was quite hot), a few of us were having dinner and most of us took something home (for us, not a dog)--and I just had a starter! Considered quite normal. Good food but there was just a lot of it and I didn't have much of an appetite.
I do know a few places that are sort of known for having portion sizes that are oriented towards people taking leftovers home.
