rndm: "Brunch" mathematically contested

Just to vent a random thought that occurred to me today.

Earlier today I was making an appointment over the phone with a friend when something (not-physical) hit me. The premises was to meet food related during a part of the day which is non-food related (breakfast, lunch or dinner). Then there is a word for brunch, namely brunch (obvious), but what if you want to have a brunch-like meal in the afternoon? As the other Seitz mentioned when I raised this vocabularic issue: there should be... (that is: if vocabularic ever becomes a word of course)

In any case our aim was to meet at around 5-6pm, which isn't dinnertime (unless you live in the Netherlands... but then again, inhabitants of that country are not qualified to have a say in this). In Korea I guess you can say that dinner is between 7pm and 9pm, anything after 9pm is considered side dishes for the alcohol(called anju in Korean) it doesn't matter if the side dishes are equal in size and nutrition as the hypothetical dinner here: before 9pm that food is called dinner with drinks, after 9pm it's called drinks with side dishes. Lunch is more or less general everywhere, set around 12 to 1pm (I can never figure out if noon is 12 am or pm, no matter how often I wikipedia it - wikipedia is now officially a verb: to wikipedia).

Thus 5-6pm does not constitute dinner, and is several hours behind lunch, which is clearly illustrated by the following:

Lunch + circa. 6h = 7pm or 8 pm or 7pm or 8 pm - circa. 6h = lunch

So if we take into account that lunch = 12 or 1 pm + food... then we can surmise that 12 or 1 pm = lunch - food !!! (this is still completely logical and as far as I know mathematically correct!)

Okay, moving on...

If 7pm or 8pm - circa. 6h = lunch and lunch = 12 or 1 pm + food

...then 7pm or 8pm - circa. 6h = 12 or 1pm + food leading to 7pm or 8pm = 12 or 1pm + food + circa. 6h end then to 7pm or 8pm - 12 or 1pm - food = circa. 6h (again! completely accurate!!!)

But! 7pm or 8pm - 12 or 1pm is clearly 6h or 7h

Thus 6h or 7h = circa. 6h!!!

Okay so what about the food... eh...

Conclusion: I spend too much time reading xkcd and now have lost the majority of my readers. Notheless the issue remains:

...

What about linner? or lunner?
