As for brunch and linner, dreakfast is to be taken between two regular meal times. It usually consists in eating some pasta, cup noodle or any other substantial and lazy food back from a club by the night bus, in order to absorb what you drank during the party, or when the said party began too early in the evening to eat a real dinner before leaving.
- Phew, there's nothing left to party and I'm still so drunk...
- You should have eaten before. The bus comes in fifteen minutes, better get back home and take a good dreakfast.
