[Jtsummers]

There are more and less literal understandings of words. Breakfast, as commonly understood, is meant as the first meal of the day, and specifically the morning meal.

Referring to your first meal, at 8pm without having slept away the day, as "breakfast" is outside most people's understanding of the word, though it is, strictly speaking, correct.

It's like the various meanings and uses of the word "decimate". The literal and historical meaning is to remove 1 out of 10 of a group, such as in combat against enemy forces or as punishment of some group or something. Today, it means removing a large percentage. "The army was decimated" today means that a large percentage (subjective) was killed or wounded.

Subjective meaning: Some might say 10% is large, others might mean 80%. And it depends on the initial size. 10% of 100 is only 10, that doesn't seem large. But 10% of 1,000,000 is 10,000, that's substantial though the percentage itself may appear small.
