Stupid openings

Where are these insane memes coming from? Why would the London be any more annoying than any other opening?

Exactly, I don't get if the london is an actually bad opening or if it is just another meme.

Usually this response comes from people too lazy to learn how to play something they already aren't familiar with.
If you claime the Halloween being unsound then it should be interesting if you give me the refutation.
At best white temporarily gets a second pawn, and sets a couple of cheap tricks- but that's all.
You mean the line 8.Qe2 Bb4 9.Bxf7 Kxf7 10.Qc4+ ?
In Rubi-Winter, Computer Chess Championship 2019 (two supercomputers both rated more than 3000 ELO) these moves were played. Rubi won 1-0

Yes, that line. Your claimed "supercomputers" are actually two experimental UCI engines, which back in 2019 did not have neural network support, and the game was 5'+2" blitz. The game has quite a few mistakes from both sides (starting from 13.Qc5 Qxc5?!), so I wouldn't claim it's worth more than two pennies.

Even the wayward queen is not listed in MCOs even as a eccentric sideline move and only seems to have become an opening in the past few decades.
The Damiano defence maybe. The fried liver as black.
For white you could say all kinds of unsound gambits like the halloween gambit or weak openings like the grob, but then again they might catch many unawares, so they could have a place.
I'll say the three knights. It's a historical opening so it's not some joke move like a3 or something, yet a very, very stupid move still. It doesn't offer any attacking chances and neither is it better at defence than just establishing your normal advantage as white. I challenge anyone to name a good reason to play 3. Nc3 that could not be answered better by playing a proper opening.
Develops your b1 knight early but still putting a pawn in the center as the first move

I think the Mosquito gambit is the worst
How bad could it be to give away your mosquitos??

One more opening is the King's Gambit Accepted: Tumbleweed Variation with a 3.11 advantage for black

IDK about you all, but if I get white, my 1st move will be e4, else e5
This is completely offtopic here.

The Irish Gambit
The Důras Gambit
The Kádas Opening: Beginner's Trap (aka hang a rook for no reason)
Actually, the Kádas Opening in general is stupid

You get a bishop for some rook which is much better at the start of the game anyway

But you have doubled pawns and no presence in the center. To make things worse, oftentimes white doesn't even take the bishop.
That is my childhood opening lol. e4 e5 d4 d5
