It means nothing = it is a bull term.

You could as well say "the house is red" but that is just so off-topic that you can't use it for an elegant disarm of a valid question.

"respect the pump" is still within of the crypto & making money subject.

That is why it works.

The term is invented by a famous crypto youtuber.

That is a salesman, and say things that are correct mixed with bull.

I can spot when he say something that is bull, so I can find some value/entertainment in some of what is true. Good training for spotting this kind of person in the future. And bull.
