@thor Maybe somebody more clever than me should make one up... I usually eat at that time of night too. I call it a snack, but it isn't.

In American English the terms "dinner" and "supper" aren't even used consistently across the country though. In some places dinner is the 2nd meal of the day while supper is the 3rd. Other places dinner and supper are synonyms for the 3rd meal, and we call the 2nd meal "lunch."
