The first meal of the day when eaten after 6pm.
Mom:"Son, Have you eaten anything all day? It's nearly 6:30"
Son:"Not yet ma, but I'll sit down and have some Brulupper in a bit."
The only meal you need, eaten at any time of day and usually very large. Usually used by people with hectic, irregular schedules.
My schedule is so busy I only have a half hour for brulupper today.
