I like Santassiere's Folly
Favourite name for a chess opening?

The Fried Liver Attack, also called the Fegatello Attack (named after an Italian idiom meaning "dead as a piece of liver")

caro-kann
for some reason I find the name really cool. I giggle thinking "caro-kanned" if somebody is beaten by this openings.
Worse one by name: hippo. I wouldn't play it even if it was good, the name just sounds ridiculous. And it's ironic because hippos are the most dangerous animals in the world.

Deer are the most dangerous due to people getting into car and motorcycle accidents with them.

How about the mosquito spreading malaria then?
I wasn't talking about accidental deaths, I was talking about the animals that would deliberately kill you on sight.

Especially if you tried to steal their babies. Never underestimate the maternal protective instinct!
QGD - always makes me think of quantum chromodynamics for some reason (except that would be quantum gromodynamics, which sounds vaguely rude).

I guess I would say homo sapiens in that case, not hippos.

@plutonia, post #9 : Max Euwe once was glad it was named Caro-Kann, as the other possibility, Kann-Caro sounds like Kangaroo.
And talking about Opening names, what about Orang Utan, Bradley Beach, Chameleon, Primitive Pillsbury, Been & Koomen, Ben-Oni (=child of my sorrow), Counterthrust, Noah's Ark Trap, Halloween, Blackburne Shilling and Corkscrew (all found in Hooper & Whyld, Oxford Companion).
And Santasiere's Folly is 1.Nf3 d5 2.b4.
A next forum could start on club names, Chicago Prairie Dogs, Cleveland Kinghunters and Washington Plumbers...

And there is always the Aged Gibbon Attack, Andersspike, Macho Grob, Beefeater variation, Big Clamp, Bayonet Attack and Goring Gambit followed by the Bled variation, Borg Gambit, Bouncing bishop variation, Brick variation, the Bullfrog, Clam Gambit, Cobra Variation, Coca-Cola Gambit, Corkscrew counter-gambit, Krazy Kat (I wrote a book on this one), Creepy Crawly, Dodo gambit, the Double Whammy, Drunken Knight Opening, Elephant Gambit, Fingerlsip variation, Frankenstein-Dracula variation, the Fred, Gaga Gambit, Giraffe Attack, Hammer Gambit, Hillbilly Attack, the Horny Defense in the KGA, Horsefly Defense, Koola-Koola, Lion's Jaw, Lizard Defense, Long Whip Variation, Mafia Defense, Maltese Falcon, Medusa Gambit, Mongoose Variation, Prickly Pawn Pass, the Pterodactyl, Scorpion Gambit, the Shirazi Shove, Snail Variation, the Spike, Vulture Defense, Wasp variation, Whale Opening, Wilds Bull Defense, the Wulumulu, and the Zot.
I have listed some of the opening names at

There is also the Mkele Mbembe, which as far as I know is the only opening name of African origin: 1 e4 Nf6 2 e5 Ne4

Excellent post @billwall, some great ones in there. I can't imagine what the "Mafia Defence" is.
I remember christening a strange hyper-defensive variation of the Hippo as the "Loch Ness Monster Defence" after I saw one of the kids I teach trying to play it, because I thought that's what I thought his pawn structure resembled! (I used the device of subtle mockery to try to encourage him to play a more sensible opening...)
I invented two appalling bad "openings" in my teens which I called the Rhinoceros Attack and the Venus Fly Trap, but unsurprisingly neither the names or the openings stuck.
Also, didn't Tony Miles once say that all openings named after animals are bad?
Not, what is your favourite opening, but specifically the name?
I ask because at work, when I should have been working, I was reading about the Modern Defense on Wiki. There is a line in the Modern called:
The Monkey's Bum.
After controlling my mirth (much to the confusion of my workmates), I read further, and found that there is line in the Monkey's Bum called:
The Monkey's Bum Deferred.
At this point I lost control of myself. I hereby vow, in a public forum, to become a master of The Monkey's Bum Deferred.
Anyway, anyone got their particular favourites?
ED.
