how and where can i get these fancy bitcoin wallet addresses ?

[Dudeperfect]

You can use following websites to generate bitcoin wallet vanity address, I haven't used any of them so be careful and do your research before going with any of these websites.

https://bitcoinvanitygen.com
https://vante.me
https://github.com/samr7/vanitygen

However, I would not recommend anyone to go with the vanity address. The best practice is to download secure, trusted github git and generating a wallet from the offline computer.

Actually, if you use vante.me then you're safe because they use split key generation. Or just use vanitygen.

but bitcoinvanitygen is someone that you should not trust. Ever. Even though they say that the private keys are only to your eyes, they might be telling a lie. Nobody knows. Some people sa ythat their coins got stolen when it was in an address registered with bitcoinvanitygen. Just not worth the risk at all.

Vanitygen is the safest option because everything can be done offline, and on your computer. Vanity addresses generated using vanitygen are as safe as bitaddress wallets.

As we all have experienced many hack incidents in the bitcoin sphere, I don't have trust on web wallet concept for the long term storage (for regular transactions they are best and user-friendly). I usually prefer to go with GitHub gits in zip files and use it on the offline computer to generate cold storage wallets.

A few years ago I got an address with my first name on it from a service called bitcoinvanitygen

I actually used it as I didn't realise or understand how dangerous that was until some dear members on the forums shouted it out and explained how the owners of that site had the same keys and the same level of access that I had.

From that day, I stopped using it completely.
But still it's something cool to show off lol

Thanks for your time.

Here to have fancy address are two possibilities .
First at may be they have created Thier account in this forum with the first two three words from Bitcoin address that they have already ( as you say ) .
Secondly may be they have created the Bitcoin address manually . I know that I said something  that which is unbelievable ( for you and for someone ) but still you can make your manual Bitcoin address ( in the starting only words ) Just go at the Google and search about paper wallet you will come across that type of step where you need to write your own words from your mind .
Here is the third option also , Thier are 2-3 sites in the internet which are providing the vip Bitcoin address ( free and premium depends upon the no. Of words you want fancy )  but I will never recommend you because the private key they will have and can scan you .
So here it is more better to use simple address instead to go in risky ways .
