Let's get it started

[Englishlanguage]

What does get somthing started exactly mean?
It sounds to me like to make something begin. Am I right?
Is it a slang expression?
Thank you.

[Casiopea]

To start or begin something. You're right.

[Englishlanguage]

Is it slang/formal/informal?

[Casiopea]

That would depend on the context. The following is used in business:

Ex: Let's get the meeting started / Let's start the meeting.

Does that help?

[Englishlanguage]

Well, yes it does. But I didn't expect that expression could be used in both formal and informal contexts.
However, thank you very much....

[Casiopea]

Informal: Let's get it started <as in a fistfight>

[Englishlanguage]

Ok. I just hope I'll never have to say something like that in such a situation!
Thank'you.
You've been very helpful.
