Brunch is just breakfast for people who don’t wake up stupid early
And it’s stupid.
How dare other people operate on different schedules than you, am I right?
I have no judgment about schedules. But I do judge brunch. And my ruling is that it’s stupid.
Say someone else had the same opinion about dinner. Or whatever meal(s) you eat. Would you cheer them on for that judgment?
Dinner is not stupid. Lunch is not stupid. Brunch is stupid.

no, brunch when you didn’t want to eat a bunch early and you don’t want to eat a second time for lunch

it is distinct from both breakfast and lunch
