What do people mean by women can have multiple orgasms?

Okay i swear i'm not dumb or one of those people that failed sex ed. I'm just curious because after i orgasm, that's it, i'm done. I'm way too sensitive. Like during oral, i will literally shove him away after i climax.

So my question is, is "multiple orgasms" just we don't have to wait like men do after they finish, if we want to go again? Or do women literally have an orgasm keep going then have another orgasm back to back?? if so, HOW?
