How about "Rich people I'm jealous of?"

So the real answer is... if you're just starting out, go mid with your gear investment.

Think it's the trap that if you continue with the hobby, all the starter gear is useless and all the money could have been spent on better equipment.

I paint miniatures. Not as often it as much as I would like to because of dividing my time between work, two year old and chores, but I have had the hobby for the last six years. I have yet to purchase an airbrush, and I can get a perfectly decent starter set for lets say 20 USD. But I can also get a better set with high end compressor, better paint gun.for 60 USD. I know that if I keep getting better at using the airbrush I will eventually get the high end stuff, why not "save" money and get it right away.

In rock climbing we use “Gumby” no clue why.

EDIT: I’d like to clarify I agree about the gatekeeping this reinforces and this really doesn’t get used often, and if anything it sees more use among friends for silly reasons, like missing a Velcro on a shoe or something. Like I said I don’t know the origin because I don’t really engage with the “joke” that much.

I've heard "wallet warrior" been thrown around in gaming communities for people who just pay for high end accounts without having any skill to back it up.

Very surprising to see so many peole lashing out at "gatekeeping". Frugality is a very important thing (something something global warming?), a beginner can not get any meaning out of the very best gear, diminishing returns are a thing.

Wasting resources because you are unable to resist the temptation of marketing is dumb, selfish and harmful.

No, of course I'm not talking about safety gear. No, I'm not advocating for buying the cheapest stuff.

Dentists.

I am so guilty of this!

Granted, if it is a new activity or hobby where rookies don't destroy gear, it makes sense to me. It lets me skip the constant upgrading as my skills increase.

I'll buy a zillion dollar airbrush and learn to use it, and feel incentivised to take care of it. I didn't do the same with my first Jeep when I got into offloading. My first one was a cheap junker that I could roll if I did a rookie move.

As for a slur for people like me....I dunno, whatever makes you feel superior I guess. If it is creative or funny enough, I'll happily adopt it and use it 👍

Rich poser back in my day

In the UK we say "All the gear and no idea"

I hate the disparaging of gatekeeping as inherently bad. Mountain biking has seen an uptick of people riding electric fat bikes, essentially just dirt bikes. It's bad enough when beginners are using normal bikes to ride in wet muddy conditions on trails that can't handle it or skidding into corners, it does so much more damage when they're tearing up the trail with a heavy motorized bike with wide tires. More gatekeeping would keep the trails in better conditions.

"Golfers"

"All the gear, no idea."

Whales. Although whales applies to people who just spend a ton of money regardless of experience.

all the gear and no idea

In the cycling community, we call them “dentists”.

At the gym, I call them "Resolutioners," and they usually only last til February.

I had a coworker who was a sneaker head (traded in limited edition shoes). They called people who bought bad deals or was generally inexpirenced "Timmys" because the persons orders looked like a kid with their parents credit card.

Isn't that just a noob?

This word already exist.

I usually just refer to them as having "more money than brains"....

Pay to fail

We see this a lot with skiing. I grew up working at mountains to afford it and my equipment is decent.

Then Joey (not sure where the name originated) will bomb past you on $5000 worth of equipment and end up in traction after wiping out on the first icy patch they see.

So the word we use is a Joey.

In cabinetmaking my teachers used to say "doctors and lawyers" and it stuck to my life outside cabinetmaking. In music there's so many people who can hardly play or only play in their basements who have gear my gigging punk ass would never even think of owning. I went to a pedal Expo recently and I had no idea what half the stuff was and I play in a couple of pretty successful bands.
