What means to ping this?

[MLLapan1]

Open CMD and write
ping 127.0.0.1 -t
press enter...

What this does?
This site says it causes high ping, but I checked and it does not do that at all.

That is pinging the local host, ie yourself. If you don't change the settings for ping it will default to small amounts of data and not use enough bandwidth.

I can't think of a legitimate reason to want to do this, so I'll let you do you own research from here.

If you flood ping yourself, then you've just DoS'd your own system. If it isn't a flood ping, it won't do much of anything. On a multicore system you might need to run more than one flood ping to self since it isn't going through a network card (127.0.0.1 is "loopback" to self and works even when there is no actual NIC on your computer).

If that is fun it might be easier to just hit one of your fingers with a hammer.

I did it to check what will it do to a ping, did I do anything bad to pc?

No and the -t means infinite ping until you stop it.

No and the -t means infinite ping until you stop it.

"No" stands as an answer on which question?

You did not hurt your pc.

Ping is harmless other than consuming resources while it runs. Ping to a remote computer consumes the network bandwidth. Ping to your own computer using 127.0.0.1 doesn't use the real network, it is entirely software. It would take lots of ping to 127.0.0.1 to have any effect ("flood" ping is the most a single computer can output in resource consumption...it is a stress test of the network...sort of a benchmark tool, although more for diagnosis of network problems). This is the basis of a DDoS though. More ping, more resource consumption (and a single computer won't have much of a load). Stop the ping and it is like nothing ever happened.
